Question

I have a query that I am trying to process, I searched it but could not find any answer, I am doing something wrong, What I want to search is, %asd%, but I get asd% result instead of it,

my fieldtype is this,

<fieldType name="text_general_edge_ngram" class="solr.TextField" positionIncrementGap="100">
        <analyzer type="index">
            <tokenizer class="solr.LowerCaseTokenizerFactory"/>
            <filter class="solr.EdgeNGramFilterFactory" minGramSize="2" maxGramSize="15" side="front"/>
        </analyzer>
        <analyzer type="query">
            <tokenizer class="solr.LowerCaseTokenizerFactory"/>
        </analyzer>
    </fieldType>

and my query is, name:asd, is it my query or field type ? thank you 🙂

If you want to make a search like %asd%, you dont need ngram filters… Basically solr uses ~ for single char and * for multiple chars in their searches…

e.g
name:asd~ will match asda asdb asdc and so on while name:asd* will matchasdasadad asdfgkhjfgkl and so on so you can use name: ~asd~ to match basdf or easdk and name:*asd* for aldkaasdsdfsd or oippopasdoppm

you dont need ngrams for this kind of search as far as i know
