Summary: Flexible "standard" query parser parses on whitespace
Key: LUCENE-7315
URL: https://issues.apache.org/jira/browse/LUCENE-7315
Project: Lucene - Core
Issue Type: Bug
Components: modules/queryparser
Reporter: Steve Rowe
Assignee: Steve Rowe
Copied from LUCENE-2605:
The queryparser parses input on whitespace, and sends each whitespace separated
term to its own independent token stream.
This breaks the following at query-time, because they can't see across
whitespace boundaries:
n-gram analysis
shingles
synonyms (especially multi-word for whitespace-separated languages)
languages where a 'word' can contain whitespace (e.g. vietnamese)
Its also rather unexpected, as users think their
charfilters/tokenizers/tokenfilters will do the same thing at index and
querytime, but in many cases they can't. Instead, preferably the queryparser
would parse around only real 'operators'.
