Manuel Lenormand created SOLR-6310:
--------------------------------------
Summary: create a TypeQueryParser to query each token on it's
matching field type
Key: SOLR-6310
URL: https://issues.apache.org/jira/browse/SOLR-6310
Project: Solr
Issue Type: Improvement
Components: query parsers
Affects Versions: 4.9
Reporter: Manuel Lenormand
Priority: Minor
Fix For: 5.0, 4.10
Indexed documents frequently contain different types in different field, e.g
emails, telephone numbers, ips etc. The fields may have been extracted from the
content field or originally structured that way.
We should propose a queryParser that recognizes the query token type (eg.
regex) and implicitly reformulate the query to run against the matching field
only. That would make a good performance boost in case the query is running on
a "catch them all" field and a more adapted analyze for the different types.
It would also avoid the idf drift that occurs on an above "catch them all"
field.
A workaround could be using the type token filter with the matching type
whitelist and querying all the different field types with edismax's qf param.
