Artem Abeleshev updated SOLR-17580:
-----------------------------------
    Description: 
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:

```
localhost:9432/solr/collection/select?fq=name:foo
localhost:9432/solr/collection/select?fq=name:bar\(baz\)
```

Also, if you combine them using `OR` query is also parsed and runned 
successfully:

```
localhost:9432/solr/collection/select?fq=name:foo OR name:bar\(baz\)
```

Adding tags to the first two queries is also OK:

```
localhost:9432/solr/collection/select?fq=\{!tag=a}name:foo
localhost:9432/solr/collection/select?fq=\{!tag=b}name:bar\(baz\)
```

But combining them with `OR` failing:

```
localhost:9432/solr/collection/select?fq=\{!tag=a}name:foo OR 
\{!tag=b}name: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:

```
localhost:9432/solr/collection/select?fq=\{!tag=a}${a} OR 
\{!tag=b}${b}&a=name:foo&b=name:bar(baz)
```

The funny thing is that if I change the order of the `OR` entries like this:

```
localhost:9432/solr/collection/select?fq=\{!tag=b}name:bar\(baz\) OR 
\{!tag=a}name:foo
```

it worked OK
