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

  1. Support correlated search on complex collections

    Now that Azure Search supports complex types, it would be useful to be able to combine full-text search and strict Boolean filters when querying over complex collections. Currently this is not possible -- search.ismatch()/ismatchscoring() are not allowed in lambda expressions, and using sub-fields of complex collections in full Lucene queries has uncorrelated semantics.

    For example, if you want to search for hotels that have deluxe rooms with city views, none of these gives you exactly what you want:

    search=Rooms/Description:(city views) AND Rooms/Type:(Deluxe Room)

    search=Rooms/Description:(city views)&$filter=Rooms/any(room: room/Type eq 'Deluxe Room')

    $filter=search.ismatchscoring('city views') and Rooms/any(room: room/Type eq 'Deluxe Room')

    Instead, what you'd…

  2. Highlight search text on blob documents

    search API should return document that should highlight search text inside the document. So that when i download view the document it should highlight search terms/text in documents like pdf, excel,word and etc.

    same like JFK it will do only for image but good to have document highlighting

  3. 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'))

  4. Support a DFS Query Then Fetch Search Type

    Support DFS Query then Fetch search type in order to get more accurate scores across shards. (Equivalent to search_type=dfs_query_then_fetch in Elasticsearch.)

  6. multi-word synonyms

    Do we have multi-word synonyms?
    If yes, can words between 2 synonym sets overlap? i.e. can I have the following 2 synonym sets:
    USA, United States
    United, together

  8. 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?

  9. 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.

  10. 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.

  11. 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.

  12. 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,

  13. 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.

  14. Support multi point Edm.GeographyPoint search

    It would be great if you could sort by nearest where documents could have an array of Edm.GeographyPoints.
    We are currently duplicating documents for every different Edm.GeographyPoint.

  15. Disable or replace TF-IDF for relevance computing

    (Posting on behalf of Xu Lan)

    To fit the needs of our search application, we would like to change the relevance computing by disabling or replacing TF-IDF.
    Elasticsearch provides a mechanism to ignore TF-IDF: https://www.elastic.co/guide/en/elasticsearch/guide/current/ignoring-tfidf.html#ignoring-tfidf.

  16. 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.

  17. 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.

  18. 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…

  19. Support 'skip' in facet queries

    Currently the results of facet queries can be limited adding the "count:n" parameter to select only the top n results.
    If one is interested in seeing all results of a facet query, there is no other way than setting the 'count' value sufficiently high to make sure that all result are included in the response.
    In the scenario of a large number of distinct values for the facet field those queries may, however, result in a large response with poor performance.
    In order to be able to provide paging through facet results for better performance, it's necessary to have a…
