Re: WordDelimiterFilterFactory with Wildcards

bq: To me this seems like a design flaw. The Solr fieldtypes seem like they allow a developer to create types that should handle wildcards intelligently. Well, that's pretty impossible. WordDelimiter(Graph)FilterFactory is a case in point. It's designed to break up on uppercase/lowercase/numeric/n

It doesn't seem to matter what you do in the query analyzer, if you have a wildcard, it won't use it. Which is exactly the behavior I observed. the solution was to set preserveOriginal="1" and change the etl process to not strip the dashes, letting the index analyzer do that. We have a lot of lega

Shawn, Thank you for that. I didn't know about that feature of the WDF. It doesn't help my situation but it's great to know about.

Hi Itay, in IR research there’s a long tradition (TREC and alike) for measuring the effectiveness of search engines. In this context it is measured by using a so called test collection, which consists of three things: 1. Documents 2. Topics i.e. information needs/queries of users for these docu

Hi, I see a lot of discussion on this topic from almost 10 years ago: e.g., https://issues.apache.org/jira/browse/LUCENE-1482 For 4.5, I relied on 'System.out.println' for writing information for debugging in production. In 6.6, I notice that some classes in Lucene are instantiating a Logger, sh
