TermsComponent terms.regex and terms.upper does not always work
---------------------------------------------------------------
Key: SOLR-2751
URL: https://issues.apache.org/jira/browse/SOLR-2751
Project: Solr
Issue Type: Bug
Components: SearchComponents - other
Affects Versions: 3.3
Environment: Solr 3.3
Reporter: Stephan Meisinger
TermComponent with a regex does check upper bound only on regexp success.
example:
terms.regex.flag=case_insensitive
terms.fl=suggest_fr
terms.limit=10
terms.regex=a.*
terms.lower=A
terms.upper=b
will also check terms starting with 'b' up to 'z'. But this wouldn't be needed.
For this example upper is ignored. Currently checks are done:
[lower] -> start loop at
[regexp] -> miss: continue
[upper] -> miss: break
[freq] -> miss: continue
should be done:
[lower] -> start loop at
[upper] -> miss: break
[freq] -> miss: continue (I think double compare is much faster then a std
regexp)
[regexp] -> miss: continue
