Azure Search

Azure Search is a search-as-a-service solution that allows developers to incorporate a sophisticated search experience into web and mobile applications without having to worry about the complexities of full-text search and without having to deploy, maintain or manage any infrastructure

How can we improve Azure Search?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Efficient way to express a true “all”

    Query with any on properties of types Collection is very easy:
    $filter=SocialAccounts/any(x: search.in(x, 'Facebook,Twitter'))

    However if you want to do the same with all you need to do something like which is not that beautifull:
    $filter=tags/any(t: t eq 'Facebook') and tags/any(t: t eq 'Twitter')

    Please implement something like:
    $filter=SocialAccounts/all(x: search.in(x, 'Facebook,Twitter'))

    • Fully covered OData filter functions

      Needed for use case like `$filter=length(title) gt 64` and/or `$filter=toupper(firstname)`

      • Provide method for escaping characters in the search string like UrlEscape

        Special characters must be escaped to be used as part of the search text. You can escape them by prefixing them with backslash (\). Special characters that need to be escaped include the following:
        + - && || ! ( ) { } [ ] ^ " ~ * ? : \ /
        Is there a built in method, basically the equivalent of UrlEscape, which can do this, or is every developer actually expected to do their own implementation?

        • Implement other highlighters

          Right now only Postings highlighter is implemented, which highlights single terms instead of full phrase query. Would be good to have other highlighters.
          As said here : https://stackoverflow.com/questions/42411353/azure-search-highlights-for-phrases-with-double-quotes

          • Return azure search feature values along with documents

            In Azure search, it would be good to return feature values used to rank documents along with documents returned. This could be used to further refine results based on user needs.

            • Search multiple indexes at once

              The underlying elasticsearch technology supports making a single search query that searches and ranks results over multiple disparate indexes at once[1], but this functionality is not surfaced through the Azure Search APIs.

              Adding this would allow a single search to span over indexes with different schemas combined in a single correctly ordered result set.

              [1]: https://www.elastic.co/guide/en/elasticsearch/reference/current/multi-index.html

              • Provide option to facet on all facetable fields in a Search request

                Some applications can have a large number of facets and it is inconvenient to have to specify them all explicitly in the Search API, as reported here: http://stackoverflow.com/questions/28542665/azure-search-what-if-i-have-a-lot-of-facets

                If there were an option like facet=* that returned facets on all facetable fields, that would be easier for such cases.

                • Support geo.distance in select result

                  Azure Search does not support returning the distance data from geo.distance in search results. geo.distance can be used in only filter and orderby.

                  I would like to get distance data from geo.distance.

                    Thank you for your feedback. While it is unlikely we’ll address this suggestion in the near future, we’ll reassess based on the number of votes it receives.

                    There are a few ways you can do this currently in code per document, for example (https://stackoverflow.com/questions/6544286/calculate-distance-of-two-geo-points-in-km-c-sharp). But we are considering how we might make it available as a document property.

                    Thanks,
                    Vinod

                  • Support scoring profiles on suggesters

                    I think it would be valuable to expand the capabilities of suggesters. Right now, they're somewhat limited. I think it would be nice if they provided the flexibility of scoring profiles. The reason why is because sometimes, it might be nice to show the most recently added or viewed documents (i.e. Edm.DateTimeOffset) as suggestions. Other times, you may want to show the most popular, or most viewed, documents (i.e Edm.Int32). These are just two scenarios that I would like to cover with suggestions, but, I'm a bit limited.

                    • Provide sum and average on facet

                      It would be nice to have agregation on certain facetable Field.
                      We would define another numeric field to be computed.

                      On the FacetResult, we could get sum and average exactly in the same way as count.

                      • Provide option to return total facet counts without all facet values included in response

                        We have facets with thousands of unique values, sometimes up to around 100k. In our UI, we'd like to show the top 10 or so values of each facet to allow the user to filter by them, but we have no need to display all 100k. That said, we need to display the facet *counts* so they know roughly how much data is being searched.

                        To do that currently, we have to set the facet counts arbitrarily high to make sure the accurate counts are retrieved, but that means we're getting back huge HTTP responses when really we just want…

                        • Add support for field collapsing

                          I've utilized field collapsing (aka result grouping) quite a bit utilizing Solr. Being able to group results together by a common element, then being able to page and sort based on that result list.

                                    Searching with text=<xyz> performs a case-insensitive search. However, testing string fields in filters is case-sensitive. There should be a way to do a case-insensitive string comparison in filter expressions.

                                    • Case-insensitive sorting for string fields

                                      When querying the index, is it possible to do a case-insensitive $orderby on a string field? For example, we want to sort results by username but preserve the user's choice of casing. While we could workaround this by keeping a normalized version of the username alongside the original data, having this feature built-in would obviously be preferable.

                                      • Improve collection matching expressions

                                        Currently, collection matching only supports simple equality for the 'any' option and inequality for the 'all' option.

                                        I would like to be able match a collection against a set of values instead of testing a single match individually and then combining the results as shown below

                                        $filter=tags/any(t: t eq 'x') and tags/any(t: t eq 'y')

                                        Additionally, it would also be useful to have the capabilities to include simple boolean logic within the lambda to craft expressions that match a collection item against slightly more complex logic for example:

                                        $filter=tags/any(t: t eq 'x' or t eq 'y')

                                          We are currently working on expanding the filter syntax available inside lambda expressions (‘any’ and ‘all’). This work is part of the work on Complex Types (currently the highest-voted User Voice item for Azure Search).

                                          Regarding the specific examples in this post, the second example is now possible using the new search.in function. For example, this:

                                          $filter=tags/any(t: t eq ‘x’) or tags/any(t: t eq ‘y’)

                                          Can now be written like this:

                                          $filter=tags/any(t: search.in(t, ‘x,y’))

                                          In the future we will also be directly supporting ‘or’ inside any/all. We will also support ‘and’ inside any/all for complex types and some primitive types, but not for collections of strings, so the example in the post above using ‘and’ will still be the only way to write that particular query.

                                          The ETA for these filter syntax changes is the same as for Complex Types, since we are delivering them together. See this post for…

                                          Why can't I import data into Azure search services? I'm using the free trial, and there's no Import Data selection on the task bar.

                                            Could you explain what you mean by ‘import data’. In Azure Portal we have ‘Import data’ command that enables you to connect to variety of data sources such as SQL Server, Cosmos DB, or blob storage. Then indexer can automatically sync data between your data source and your search index.
