Query_string can't find token that _analyze shows is generated, but term query can

Elastic Stack Elasticsearch
1

I have attached a short bash script to recreate the situation. I have a
fairly simple custom analyzer that I want to break on camel case so
lowercase is last. Using the _analyze endpoint I can see the token I am
searching for is generated by the analyzer, however searching for it with
query_string yields a different result that a term query. I put comments in
the script to explain in more detail.

Thanks for any help!

I suspect the issue is the way the query parser works. The query phrase
"exampleof bug" will be parsed into a query for the tokens "exampleof" and
"bug" that are adjacent to each other. The issue is that you do not have
two such tokens, instead you have a token with the value "exampleof bug",
which is a single token with a space in it. According to Lucene, they are
not the same thing. You would need to create an analyzer that would create
the tokens "exampleof" and "bug".

Cheers,

Ivan

But the query is this...

name:"exampleof bug"

This should find an exact match in the field name. That exact match token
exists.

The syntax for lucene under "Fields" section shows a double quote is the
correct character for
this. Apache Lucene - Query Parser Syntax The term
query is found by query_string when using single quotes, but that doesn't
match lucene query documentation.

Thanks!

The query string query is a phrase query ""exampleof bug""
The term query is looking for a single token "exampleof bug"

The query parser will not use your tokenizer to parse the phrase. It will
tokenize based on whitespace and then apply the filters to each term. Your
index does not contain the token "exampleof" and your analyze API example
confirms it. The issue of the query parser is a long standing one in Lucene.

Well crap. By creating tokens that match it eliminates the exact match I'm
trying correct?

If I indexed two documents with each of the strings below... (assuming the
tokens are generated as you stated above)

exampleof bug
exampleof sample bug

Then ran a query:

name:"exampleof bug"

Would return both documents, which isn't an exact match but equivalent to
these queries.

name:exampleof bug
name:exampleof OR bug

Thanks!

In general, if you are using the keyword tokenizer or non analyzed fields,
then query string queries should probably not be used. Phrase queries and
the keyword tokenizer also do not mix well.

Your OR queries succeed because "bug" is a token in your index.

In the ES documentation is talks about escape characters and space is one
of them. Seems like if you escaped the query with a "\ " it would ignore
that during the parsing.

Thanks for your help.

This should find an exact match in the field name. That exact match

The syntax for lucene under "Fields" section shows a double quote is
the correct character for this. Lucene Java Documentation
queryparsersyntax.html The term query is found by query_string when
using single quotes, but that doesn't match lucene query documentation.

Thanks!

I suspect the issue is the way the query parser works. The query
phrase "exampleof bug" will be parsed into a query for the tokens
"exampleof" and "bug" that are adjacent to each other. The issue is that
you do not have two such tokens, instead you have a token with the
value "exampleof bug", which is a single token with a space in it.
According to Lucene, they are not the same thing. You would need to create
an analyzer that would create the tokens "exampleof" and "bug".

One more thing! The match query does not go through the query parser phase.

The query parser will not use your tokenizer to parse the phrase. It
will tokenize based on whitespace and then apply the filters to each term.
Your index does not contain the token "exampleof" and your analyze API
example confirms it. The issue of the query parser is a long standing one
in Lucene.

Interesting! If that supports straight lucene syntax then this is golden.
Our system must support full lucene syntax along with "fuzzy" searches
which is why I've been using query_string.

Thanks!
