Re: Stopwords impact on search

IDF and stopword removal are different approaches to the same thing. Removing stopwords is a binary decision on how important common words are for search. It says some words are completely useless. IDF is a proportional measure on how important common words are for search. Instead of removing a

Re: Stopwords impact on search

Hi everyone, I get it why and when if stopwords are note indexed is a bad idea and can give you 0 or incomplete results. But what about the quality of search result when stopwords are indexed vs. not indexed? 1) Stopwords are removed and I do word search, not phrase for "solr and lucene are so c

Hi, Our clients are running streaming expressions on 140M docs collection which has relatively huge data however query is not completing through & timing out after 120secs (which is default timeout in jetty*.xml files). We had changed the default timeout from 120s to 300s which worked fine. To

Re: using S3 as the Directory for Solr

Its 10 PB of source data, But we do have indexes on most of the attributes. 80% or so We have a need to support such large data and we have use cases of finding a needle in the haystack kinda scenario. Most of our users are used to Search query language or Solr in addition to SQL. So we would have

I’m astonished that the default still has that. It was a bad idea in Solr 1.3, when it bit my ass. We help people with this about once a month and the advice is always the same. Imagine all the poor people who never ask about it and run with that default! wunder Walter Underwood wun...@wunderwoo

Agreed. Here is an article from 13 years ago when I accidentally turned on stopword removal at Netflix. It caused bad problems. https://observer.wunderwood.org/2007/05/31/do-all-stopword-queries-matter/ Infoseek was not removing stopwords when I joined them in 1996. Since then, I’ve always left

Re: "Error creating core. No system property or default value specified for X"

Screenshots do not come through, the mail server pretty aggressively strips them. Ok, this is weird. There’s no way you should be getting results from an index that has only a write.lock file. So the fact that you were suggests that you are looking. at one thing and Solr is looking at another.
