Hello Everyone, I'm new to elasticsearch and I'm doing some experiments with the completion suggest feature. I was wondering if using a string array as 'input' parameter when indexing, as in the example on the guide "input": ["Nevermind", "Nirvana"] is there anyway to use multiple prefixes in the suggest query? Something like: { "song-suggest" : { "text" : "nev nir", "completion" : { "field" : "suggest" } } } Or is there any mapping for the completion type that would allow a similar suggest query?

so you want us to expand all the term in you query? I think you should send multiple prefix requests instead one with "nir" one with "nev". I really can't entirely figure out when you would have a need for something like this to be honest. can you provide a usecase that migh tmake it easier to help you. simon On Wednesday, August 21, 2013 12:16:23 PM UTC+2, [wron...@gmail.com](mailto:wron...@gmail.com) wrote: > Hello Everyone, > > I'm new to elasticsearch and I'm doing some experiments with the > completion suggest feature. > I was wondering if using a string array as 'input' parameter when > indexing, as in the example on the guide > > "input": ["Nevermind", "Nirvana"] > > is there anyway to use multiple prefixes in the suggest query?

By multiple prefix request do you mean something like { "song-suggest" : { "text" : "nev", "completion" : { "field" : "suggest" } } "song-suggest2" : { "text" : "nir", "completion" : { "field" : "suggest" } } } Is there a way to use an AND operator on the results of the two requests? The use case would be searching for more than one prefix at a time, possibly "out of order" Given an input like the following one, a possible query would be on "smell spir". "input": ["smell", "like", "teen", spirit"] But it's probably not what the completion suggest was meant for.

Let's say I have two documents, the first one "input": ["smells", "like", "teen", "spirit"] "output": "Smells like teen spirit" and the second one "input": ["smells", "like", "children"] "output": "Smells like children" I'd like to search with more than one prefix at once. Searching for "smel" and "spir" together should return "Smells like teen spirit" It the title is a string field indexed with a standard analyzer it is possible to use a prefix filter for each of the search terms and combine them with an and filter. Is there a way to obtain a similar thing with the completion suggest? Thanks On Wednesday, 21 August 2013 13:28:22 UTC+1, simonw wrote: > > > so you want us to expand all the term in you query?

Searching for > "smel" and "spir" together should return "Smells like teen spirit" see, this is what I want to understand... what is the usecase that you need to do that? who would type two prefixes? I don't want to say that this is wrong I just wanna understand it to give you better advice... I'd expect that you get one prefix that could be somewhere in the phrase but that is a different problem with different solutions. simon > It the title is a string field indexed with a standard analyzer it is > possible to use a prefix filter for each of the search terms and combine > them with an and filter. > Is there a way to obtain a similar thing with the completion suggest? > Thanks > > On Wednesday, 21 August 2013 13:28:22 UTC+1, simonw wrote: > > > > > so you want us to expand all the term in you query?

It would be an the ability for a user to narrow the search results while typing, but using any word in the phrase he's looking for. The first word would probably be a complete term, not a prefix, when he starts typing the second term. For the titles example, it would be someone that starts looking for "smells" and after getting the results, he starts typing "chil" for example, to narrow the results. What would be the best approach to this kind of use case? And what would be the best way to get a prefix somewhere in the phrase?

I guess a edgeNGram approach would be the best for this. I still don't see why I'd type "chil" after "smells" if you already display me "smells like children" as a query so I can just select it and fire the search. This service is more of a query suggestion like you get in google when you start typing. simon > Thanks > > > It the title is a string field indexed with a standard analyzer it is > > possible to use a prefix filter for each of the search terms and combine > > them with an and filter. > > Is there a way to obtain a similar thing with the completion suggest? > > > Thanks > > > > On Wednesday, 21 August 2013 13:28:22 UTC+1, simonw wrote: > > > > > > > so you want us to expand all the term in you query?

Yes, it's displaying the results while typing. I've tried the approach with edgeNGram and the one using prefix filters. The edgeNGram was surprising, because it wasn't much faster than the prefix approach. I think I'll go with the prefix approach, because the performance gain with the edgeNGram doesn't seem worth the increased index size. The completion suggest seems much faster, that's why I was trying to make it works in this case. It's returning the top results for "smells" while typing, so maybe "smells like children" it's not displayed searching just for "smells". But I agree that is probably a strange use case.
