--------------------------------------
Summary: Dynamic query analyze chain
Key: SOLR-5053
URL: https://issues.apache.org/jira/browse/SOLR-5053
Project: Solr
Issue Type: Improvement
Components: query parsers, Schema and Analysis
Affects Versions: 4.3.1
Reporter: Manuel Lenormand
Priority: Minor
Fix For: 4.5
Give the ability to decide during query time which analysis chain a specific
query should under go.
Typical use case is a multi-language index that is not indexed to a field for
each language (or cannot due to multi-language docs or resource limitation).
Although the text during index time goes through stemmers of language A and
language B, there's no reason for a user quering in language A having to under
go a stemmer of language B - this would definitely lower down the precision.
Another use case is if the user does not wish his specific query to get
N-grammed / synonymed or any other process that the standard analysis during
query does.
A query parser implementation should enable quering a dummy field (or
fieldType) and after the latter's analysis the analysed query would run against
another field.
