Lakshmi Venkataswamy commented on SOLR-4824:
--------------------------------------------
I have tested 4.5.0 version and the same behavior has been observed. So we are
staying with 3.6 in production for now.
> Fuzzy / Faceting results are changed after ingestion of documents past a
> certain number

> Key: SOLR-4824
> URL: https://issues.apache.org/jira/browse/SOLR-4824
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.2, 4.3
> Environment: Ubuntu 12.04 LTS 12.04.2
> jre1.7.0_17
> jboss-as-7.1.1.Final
> Reporter: Lakshmi Venkataswamy
>
> In upgrading from SOLR 3.6 to 4.2/4.3 and comparing results on fuzzy queries,
> I found that after a certain number of documents were ingested the fuzzy
> query had drastically lower number of results. We have approximately 18,000
> documents per day and after ingesting approximately 40 days of documents, the
> next incremental day of documents results in a lower number of results of a
> fuzzy search.
> The query :
> http://10.100.1.xx:8080/solr/corex/select?q=cc:worde~1&facet=on&facet.field=date&fl=date&facet.sort
