I'm trying to use ES's search lite
[http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/search-lite.html](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?

Use URI escaping (percent encoding). It is perfectly described on the page

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`.

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/](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
