Definitly using fastVectorHighlighter with wildcards in hl.fl causes
unacceptable QTimes.
> High QTime when wildcards in hl.fl are used

> Key: SOLR-4540
> URL: https://issues.apache.org/jira/browse/SOLR-4540
> Project: Solr
> Issue Type: Bug
> Components: highlighter
> Affects Versions: 4.1
> Environment: Debian 6, Java 1.6.0_26 (Oracle)
> Reporter: Karol Sikora
>
> I have indexed documents with fileds named like fulltext_[some id].
> I'm testing highlighting on document which have only one that field,
> fulltext_1234.
> When 'fulltext_*' is provided as hl.fl, QTime is horribly big (> 10s), when
> explicit 'fulltext_1234' is provided, QTime is acceptable (~30ms).
> I'm using fastVectorHighliter in both cases.
