Re: tf function query
sorry guys to have not been responding & thanks a lot for answers. @Erick Erickson: what I would ideally like to have is tf-idf value for user's query. The thing is that we have two searchable fields. While boost works just fine for one, there is no easy way to have it multiplied by boost from another field (with current parser). @Erik Hatcher: interesting idea, how have I missed it :) Is there a way to capture the value and push it through to other field's boost function?

Re: tf function query
What would you expect as output? tf(field, "a OR b AND c NOT d"). I'm not sure what term frequency would even mean in that situation. tf is a pretty simple function, it expects a single term and there's now way I know of to do what you're asking.

Re: tf function query
How about the query() function? Just be clever about the query you specify ;) > On Oct 5, 2017, at 06:14, Dmitry Kanwrote: > > Hi, > > According to > https://lucene.apache.org/solr/guide/6_6/function-queries.html#FunctionQueries-AvailableFunctions > > tf(field, term) requires a term as a second parameter.

RE: tf function query
I am afraid this is not possible, since getting frequencies for phrases is not possible, unless the phrases are created as tokens (i.e. using n-grams or shingles) and indexed. If someone has a solution for this, then I am interested as well. /JZ -Original Message- From: Dmitry Kan [mailto:solrexp...@gmail.com] Sent: Thursday, October 5, 2017 12:15 PM To: solr-user@lucene.apache.org Subject: tf function query Hi, According to https://lucene.apache.org/solr/guide/6_6/function-queries.html#FunctionQueries-AvailableFunctions tf(field, term) requires a term as a second parameter.

tf function query
Hi, According to https://lucene.apache.org/solr/guide/6_6/function-queries.html#FunctionQueries-AvailableFunctions tf(field, term) requires a term as a second parameter. Is there a possibility to pass in an entire input query (multiterm and boolean) to the function? The context here is that we don't use edismax parser to apply multifield boosts, but instead use a custom ranking function. Would appreciate any thoughts, Dmitry -- Dmitry Kan Luke Toolbox: http://github.com/DmitryKey/luke Blog: http://dmitrykan.blogspot.com Twitter: http://twitter.com/dmitrykan SemanticAnalyzer: https://semanticanalyzer.info
