Wild Card Search on Analyzed fields

Elastic Stack Elasticsearch
1

We are unable to provide wildcard based search on anlyzed fields

We want to impliment starts with and endswith functionality for the fields
Consider the following document
{
"fid": 175764,
"eval": null,
"tval": "multi Layered mobile screen",
"sval": null,
"cval": null,
"ival": "",
"nval": "",
"modd": "2014-01-01",
"modu": "polaris virtusa"
}

Here field "tval" uses statndard analyzer for indexing
if user serches for tval = "^multi layered", above document to be return as it starts with same set of terms
if user serches for tval = "mobile screen^", above document to be return as it ends with same set of terms

We are unable to implement above functionality on analyzed fields
is there any way to achieve this ?

Note : using ES 2.2

I think you'll need to also index that field as unanalyzed if you want wildcard queries to work on the entire string.

Separately, I don't think ES accepts the ^ for begin/end anchoring.

See https://www.elastic.co/guide/en/elasticsearch/guide/current/_wildcard_and_regexp_queries.html for details.

Thank you mike
I think not analyzed would solve my problem
