Question regarding getting back results from middle of word

[Karl Kildén <ka...@gmail.com>]

Hello!

if I have a field like "onetwothreefour" I want users to find that document
with a query for "two". This seems to work when I use

                        <filter class="solr.ReverseStringFilterFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="3"
maxGramSize="25" />
<filter class="solr.ReverseStringFilterFactory"/>

I got that one off google. The problem is I really want a search for "one"
to be regarded as a better hit but seems the fragments created are like an
equal word, or am I missing something? I also don't want those fragments to
be a part of the spelling index...

Feels like I am missing something on how to best configure wildcards in a
word yet not affecting my index.

Cheers

It sounds the classic XY problem , can you explain us a little bit better
your problem ?
Why you have such strange field content, how do you produce it ?
Can this be solved with an analysis ad hoc for your language ?

It sounds to me as a tokenization problem, and you are not going to solve
it using edge grams …

Please give us more details,

Cheers
