Hi everyone. I have the task of converting our old SOLR 4.10.2 instance to the current SOLR 7.6.0 version. We're using SOLR as our Search API backend for a Drupal 7 Commerce web site. One of the most basic queries is that a customer would enter a part number or a portion of a part number on our web site and then get a list of part numbers back. Under the hood, we are using the "search_api_solr" module for Drupal 7 which produces a rather large query request. I have simplified a sample request for the sake of this discussion.
On SOLR 4.10.2, when I issue the following to our core: /select?qf=tm_field_product^21.0&qf=tm_title_field^8.0&q=ac6023*&wt=xml&rows=10&debugQuery=true I get 32 rows returned (out of a 1.4M indexed documents). Here is a link to the response (edited to focus on debugging info): https://pastebin.com/JHuFcbGG <https://pastebin.com/JHuFcbGG> Notice how "parsedQuery" has a proper DisjunctionMaxQuery based on the two query fields. Now starting from SOLR version 5+, I receive zero (0) results back, but more importantly, the Query Parser produces an empty parsedQuery. Here is the same query issued to SOLR 7.6.0 (current version): https://pastebin.com/XcNhfdUD <https://pastebin.com/XcNhfdUD> Notice how "parsedQuery" now shows "+()"; an empty query string. As I understand it, the wildcard is a perfectly legal character in a query and has the following meaning: http://lucene.apache.org/solr/guide/7_6/the-standard-query-parser.html#wildcard-searches <http://lucene.apache.org/solr/guide/7_6/the-standard-query-parser.html#wildcard-searches> So why does this not work? I have installed SOLR 5.5.5 and 6.6.5 as well just to test when this behavior started happening, and it starts as early as SOLR 5. I've been searching Google for the past week now on the matter and cannot for the life of me find an answer to this issue. So I am turning to this mailing list for any advice and assistance. Kind regards, and thanks. Kay -- The information in this e-mail is confidential and is intended solely for the addressee(s). Access to this email by anyone else is unauthorized.
