-----------------------------------
Summary: eDisMax Field Aliasing behaving oddly when invalid field
is present
Key: SOLR-5052
URL: https://issues.apache.org/jira/browse/SOLR-5052
Project: Solr
Issue Type: Bug
Components: query parsers
Affects Versions: 4.3.1
Environment: AWS / Ubuntu
Reporter: Trey Grainger
Priority: Minor
Fix For: 4.5
Field Aliasing for the eDisMax query parser behaves in a very odd manner if an
invalid field is specified in any of the aliases. Essentially, instead of
throwing an exception on an invalid alias, it breaks all of the other aliased
fields such that they will only handle the first term correctly. Take the
following example:
/select?defType=edismax&f.who.qf=personLastName_t^30
personFirstName_t^10&f.what.qf=itemName_t
companyName_t^5&f.where.qf=cityName_t^10 INVALIDFIELDNAME^20 countryName_t^35
postalCodeName_t^30&q=who:(trey grainger) what:(solr) where:(atlanta,
ga)&debugQuery=true&df=text
The terms "trey", "solr" and "atlanta" correctly search across the aliased
fields, but the terms "grainger" and "ga" are incorrectly being searched across
the default field ("text"). Here is parsed query from the debug:
<lst name="debug">
<str name="rawquerystring">
who:(trey grainger) what:(solr) where:(decatur, ga)
</str>
<str name="querystring">
who:(trey grainger) what:(solr) where:(decatur, ga)
</str>
<str name="parsedquery">
(+(DisjunctionMaxQuery((personFirstName_t:trey^10.0 |
personLastName_t:trey^30.0)) DisjunctionMaxQuery((text:grainger))
DisjunctionMaxQuery((itemName_t:solr | companyName_t:solr^5.0))
DisjunctionMaxQuery((postalCodeName_t:decatur^30.0 | countryName_t:decatur^35.0
| cityName_t:decatur^10.0)) DisjunctionMaxQuery((text:ga))))/no_coord
</str>
<str name="parsedquery_toString">
+((personFirstName_t:trey^10.0 | personLastName_t:trey^30.0) (text:grainger)
(itemName_t:solr | companyName_t:solr^5.0) (postalCodeName_t:decatur^30.0 |
countryName_t:decatur^35.0 | cityName_t:decatur^10.0) (text:ga))
</str>
I think the presence of an invalid field in a qf parameter should throw an
exception (or throw the invalid field away in that alias), but it shouldn't
break the aliases for other fields.
For the record, if there are no invalid fields in any of the aliases, all of
the aliases work. If there is one invalid field in any of the aliases, all of
the aliases act oddly like this.
