Hi everyone, I am pretty new to ES and need some advice for the following use case: I have a unique input field for user search (Google like). In my test index, I have two different types, let's call them "rent" and "buy". What I would like to achieve is leverage ES's full-text powerful features to determine which index type to query depending on the query (part of it).
For instance, for a query such as "rent a motorcycle in Paris" or "hire a flat in Rome" => is there a way to have ES "know" it should look into the "rent" type? I thought of a first possibility: query both types (/rent,buy/_search) then filter on a (quite redundant) "type" field created each time a document is indexed, this "type" field being applied the proper analyzers/synonyms to always simplify things to "rent" or "buy". (or more directly the "_type" field but I don't think you can apply analysis to it, can you?) The "cons" to this approach is that I have to query both the rent and the buy types then filter to narrow the results to the expected type of documents. The "pros" is that it should not be complicated to have it work properly. Now, I am wondering if it would be possible to have ES "figure out" what index to query right after analysis? In a process like: query => analysis => "rent" or "buy" term identified => perform on the right index type. The pros would be that you obviously query one index type thus don't need to filter afterwards: smaller data set + no filtering, should be lighter/faster. The cons: I do not think that ES can do it. Another scenario would be to handle a first, app specific analysis step before querying ES just to determine "rent" or "buy". With this example it would not be that tough (two types, a few synonyms/a bit of stemming to take into account, etc.), but with a more complex setup it would become a real nightmare - not to mention the fact that not using ES's abilities would be quite a pity, actually... I would really appreciate your thoughts on this, you all :-) Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
