Hello, I am trying to use a term filter but i don't receive any results and i think the problem is due to the use of 'special' characters... My search item has a property called "code" with a value "test#b7ee8e9f-acd6-489b-b37f-d9c651f1b23b" In my mapping, i specify the analyzer to be simple in order not to loose the "special" characters as follows: .startObject("code") .field("analyzer", "simple") .field("type", "string") .endObject() I have tried to use the code property in a term filter both i don't get any results. I've also tried to escape the special characters (as described [http://lucene.apache.org/core/old\_versioned\_docs/versions/3\_4\_0/queryparsersyntax.html#Escaping%20Special%20Characters](http://lucene.apache.org/core/old_versioned_docs/versions/3_4_0/queryparsersyntax.html#Escaping%20Special%20Characters)) but that didn't change anything. What am i doing wrong please? Thanks! Stik -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Term filters terms are not analyzed, so it should be applied against a field that is not-analyzed or with KeywordAnalyzer. -- Ivan On Wed, May 1, 2013 at 9:46 AM, Stik kos [stikkos@gmail.com](mailto:stikkos@gmail.com) wrote: > Hello, > > I am trying to use a term filter but i don't receive any results and i > think the problem is due to the use of 'special' characters... > > My search item has a property called "code" with a value > "test#b7ee8e9f-acd6-489b-b37f-d9c651f1b23b" > > In my mapping, i specify the analyzer to be simple in order not to loose > the "special" characters as follows: > > .startObject("code") > .field("analyzer", "simple") > .field("type", "string") > .endObject() > > I have tried to use the code property in a term filter both i don't get > any results.
