Examine Search, how to use fuzzy ?
Hi,

I'm using this query which is working fine.
```
// Query
var searchQuery = searchCriteria.Field("excludeFromSearch", "0").Or().Field("excludeFromSearch", "").And()
.GroupedOr(new string[] { "nodeName", "nodeTypeAlias", "bodyText", "metaDescription"}, searchString)
.Compile();
```
But I dont want it to make an "hard" search for the searchstring.. f.ex if I search for "title on page" I will find the page but with "title on pa" I will not find the page. I figure I need to have fuzzy option to extend the area of the search but I can't figure out where to insert it ".Fuzzy()".

Any suggestions would be appreciated !

Hi,

You don't need fuzzy in this instance you need wildcard so where you are searchString change that to
```
searchString.MultipleCharacterWildcard()
```
Also if the index is built using standard analyzer the word "on" will not be in the index as its a stop word. Also in examine if your search term contains spaces you need to separate out the words so you would need code like
```
            if (searchString.Contains(" "))
            {
                string[] terms = searchString.Split(' ');
                searchQuery.And().GroupedOr(new List<string>{"bodyText"}, terms);

            }
```
Also you would need to do it for each field you are searching on. One thing I would recommend is to use ezSearch package http://our.umbraco.org/projects/website-utilities/ezsearch it handles all this kind of stuff and just works out of the box.

Regards

Thank you Ismail !

I don't get the option for "MultipleCharacterWildcard()" and get there for an error, I'm using Umbraco 6.1.6.

   var searchQuery = searchCriteria.Field("excludeFromSearch", "0").Or().Field("excludeFromSearch", "").And()
        .GroupedOr(new string[] { "nodeName", "nodeTypeAlias", "bodyText", "metaDescription"}, searchString.MultipleCharacterWildcard())
        .Compile();

No problem, found it :)
```
Examine.LuceneEngine.SearchCriteria.LuceneSearchExtensions.MultipleCharacterWildcard(searchString)
```
