Summary: Query parser problems when using tags and escaping
Key: SOLR-17580
URL: https://issues.apache.org/jira/browse/SOLR-17580
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: query parsers
Affects Versions: 9.6.1
Reporter: Artem Abeleshev
It seems there are some problems with query lexical analyser parsing queries
mized with `tag` directives and escaping. Here is what I've got:
If you run queries below they are running successfully:
```
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=annkennsute_tasu:foo
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=annkennsute_tasu:bar\(baz\)
```
Also, if you combine them using `OR` query is also parsed and runned
successfully:
```
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=annkennsute_tasu:foo
OR annkennsute_tasu:bar\(baz\)
```
Adding tags to the first two queries is also OK:
```
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=\{!tag=a}annkennsute_tasu:foo
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=\{!tag=b}annkennsute_tasu:bar\(baz\)
```
But combining them with `OR` failing:
```
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=\{!tag=a}annkennsute_tasu:foo
OR \{!tag=b}annkennsute_tasu:bar\(baz\)
```
sending back error response:
```json
{
"responseHeader":{
"status":400,
"QTime":0,
"params":{
"fq":"\{!tag=a}name:foo OR \{!tag=b}name:bar\\(baz\\)"
}
},
"error":{
"metadata":["error-class","org.apache.solr.common.SolrException","root-error-class","org.apache.solr.parser.TokenMgrError"],
"msg":"org.apache.solr.search.SyntaxError: Cannot parse 'name:bar\\(baz\\':
Lexical error at line 1, column 16. Encountered: <EOF> (in lexical state 3)",
"code":400
}
}
```
The same effect if using variables:
```
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=\{!tag=a}${a}
OR \{!tag=b}${b}&a=annkennsute_tasu:foo&b=annkennsute_tasu:bar(baz)
```
The funny thing is that if I change the order of the `OR` entries like this:
```
https://byside-dev-solr.i.kandasearch.com/solr/transfer-deal/select?fq=\{!tag=b}annkennsute_tasu:bar\(baz\)
OR \{!tag=a}annkennsute_tasu:foo
```
it worked OK
