Unified Search - Using AnyWordBeginWith on all fields

Vote:

Is it possible to use wildcard or AnyWordBeginWith filter on the UnifiedSearchFor method?

I took a look at the elastic search documentation which says wildcard characters are can be used as * but adding this onto the end of the words I pass to UnifiedSearchFor() does not appear to work.

I can see there are example of performing wildcard and fuzzzy queries by Joel and Henirck but these are performed at a field level, not across all feilds when using UnifiedSearchFor() method.

Is this possible, or should it not be done because of the performance hit.

Thanks,

Adam

You cannot use wildcards in UnifiedSearchFor directly as it will be interpreted as the char * and not the 'wildcard'. What you can do is create your own For extension that supports this:

public static IQueriedSearch<TSource, QueryStringQuery> WildcardFor<TSource>(
this ITypeSearch<TSource> search, string queryString)
{

return new Search<TSource, QueryStringQuery>(search, context =>
{
var query = new QueryStringQuery(searchQuery);

context.RequestBody.Query = query;

});
}

Thanks Henrick - works great :)

Just one little mistake on the seachQuery variable name, think it should be queryString

        public static IQueriedSearch<TSource, QueryStringQuery> WildcardFor<TSource>(
            this ITypeSearch<TSource> search, string queryString)
        {
            
            return new Search<TSource, QueryStringQuery>(search, context =>
            {
                var query = new QueryStringQuery(queryString); context.RequestBody.Query = query;
            });
        }

Best bets doesn't seem to work when this extension method is applied, have you noticed this too Adam?
