-----------------------------------
Summary: Support wildcard & co in PostingsHighlighter
Key: LUCENE-5415
URL: https://issues.apache.org/jira/browse/LUCENE-5415
Project: Lucene - Core
Issue Type: Improvement
Components: modules/highlighter
Reporter: Robert Muir
PostingsHighlighter uses the offsets encoded in the postings lists for the
terms to find query matches.
As such, it isn't really suitable for stuff like wildcards for two reasons:
1. an expensive rewrite against the term dictionary (i think other highlighters
share this problem)
2. accumulating data from potentially many terms (e.g. reading many postings)
However, we could provide an option for some of these queries to work, but in a
different way, that avoids these downsides.
Instead we can just grab the Automaton representation of the queries, and match
it against the content directly (which won't blow up).
