Yes, you can select a tokenizer for controlling how to split words.
If you index "bar-baz", you index two words, bar and baz, because standard
analyzer delimits tokens according to Unicode text segmentation rules in
http://unicode.org/reports/tr29/
So the easiest method to use standard tokenizer is probably by phrase
search, and it works like this:
PUT /test/doc/1
{
"foo" : "bar"
}
PUT /test/doc/2
{
"foo" : "bar-baz"
}
GET /test/_refresh
GET /test/_search?q=%22bar%2Dbaz%22

Percent encoding the string appears to make no difference. Passing in
"+foo:bar-baz” or "%2Bfoo%3Abar-baz” yields exactly the same resultset.
Is this potentially to do with the analysis of the strings in question?
For instance - I assume by not analysing the foo field the propensity to
return ‘similar’ results will be removed as ES won’t have done the analysis
on the parts of the word?
For instance: /_analyze?text=foo-bar yields something different to say
/_analyze?text=foo-bar&analyzer=whitespace.

I'm trying to use ES's search lite
http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/search-lite.html to
query a dataset which contains a key foo. An example of this is:
.../_search?q=+foo:bar-baz
Now, my understanding is is that the addition of + to the foo attribute
should make this search return only exactly matches where foo is bar-baz.
However, I'm finding that I'm also getting other results coming back, for
instance foo-baz or baz-baz etc.
What am I doing wrong here which is causing these other results to be
returned? How can I resolve this?
