Re: Boolean Searches?
Dave, You don't mention what query parser you are using, but with the default query parser you can field qualify all the terms entered in a text box by surrounding them with parenthesis. So if you want to search against the 'title' field and they entered: train OR dragon You could generate the Solr query: title:(train OR dragon) Historically however Solr has not processed queries that contain a mixture of boolean operators as expected. The problem is described here: http://robotlibrarian.billdueber.com/2011/12/solr-and-boolean-operators/ There is an open JIRA for this ( https://issues.apache.org/jira/browse/SOLR-4023) so I assume the problem still exists in the most recent releases.

Re: Boolean Searches?
If you make your default operator "OR", or the q.op, and also use the edismax query parser you can use the qf field to boost the title heavily compared to the default field you are using, for example i use something like this, which may be over kill: title^100 description^50 topic^30 text i also have the same in my pf value as well but it works for me.

Boolean Searches?
Hi Everyone, I'm building a SOLR search application and the customer wants the search to work like google search. They want the user to be able to enter boolean searches like: train OR dragon. which would find any matches that has the word "train" or the word "dragon" in the title. I know that the SOLR search would like this: title:train OR title:dragon I am trying to avoid having to parse through what the user enters and build out complex search strings. Is there any way that I can build a search against the "title" field where if the user enters something like: train OR dragon AND 2 it will hour the boolean AND/OR logic without my having to convert it into somethng nasty like: title:train OR title:dragon AND title:2 Thank you! -- *Fig Leaf Software, Inc.* https://www.figleaf.com/ <https://www.figleaf.com/> Full-Service Solutions Integrator
