Re: Autocomplete returning shingles
Yes, faceting will work, you can use an old approach used for autocompletion[1] . Be sure you add the shingle filter to the appropriate index time analysis for the field you want. Facet values are extracted from the indexed terms, so calculating faceting and filtering by prefix should do the trick.

Re: Autocomplete returning shingles
Yes, splitting in more documents would probably work. Don't think I can do this easliy with Solr. Looking into using facets now. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: Autocomplete returning shingles
So, your problem is you want to return shingle suggestions from a field in input but apply multiple filter queries to the documents you want to fetch suggestions from. Are you building an auxiliary index for that ? You need to design it accordingly. If you want to to map each suggestion to a single document in the auxiliary index, when you build this auxiliary index you need to calculate the shingles client side and push the multiple documents ( suggestion) per original field content. To do that automatically in Solr I was thinking you could write an UpdateRequestProcessor that given in input the document, split it in multiple docs, but unfortunately the current architecture of UpdateRequestProcessors takes in input 1 Doc and and returns in output just 1 doc. So it is not a viable approach. Unfortunately the shingle filter here doesn't help, as the user want shingle in output ( analysers doesn't affect stored content) Cheers - --- Alessandro Benedetti Search Consultant, R Software Engineer, Director Sease Ltd. - www.sease.io -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Re: Autocomplete returning shingles
Can you just add the SingleFilter to your field? https://lucene.apache.org/solr/guide/6_6/filter-descriptions.html#FilterDescriptions-ShingleFilter On Wed, May 2, 2018 at 2:04 PM, O.

Autocomplete returning shingles
I need to use autocomplete with edismax (ngrams,edgegrams) to return shingled suggestions. Field value "new york city" needs to return on query "ne" -> "new","new york","new york city". With suggester this is easy. But im forced to use edismax because I need to apply mutliple filter queries. What is best approach to deal with this? Any suggestions are appreciated. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
