Hoss,
before I ran into some missunderstandings, I want to come back to topic
first. I will have a look at some classes later, to find out whether some
other ideas which are not directly related to this topic (like the
multiword-synonyms at query-time) will work or not. I'm sorry for beeing
off-topic.

Okay, as I have understood you mean something like this:
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.SynonymFilterFactory"
synonyms="synonyms.txt"
ignoreCase="true" expand="false"/>
<filter class="solr.WordDelimiterFilterFactory"
generateWordParts="1"
generateNumberParts="1"
catenateWords="0"
catenateNumbers="0"
catenateAll="0"
splitOnCaseChange="1"/>
<filter class="my.TokenCountingTokenFilter"/>
This fieldType should "store" (or let's say index) the number of tokens as
something like "005" for 5 token, right?
My problem is that I don't know how to query this field.
I know what you mean with appending the query with "Add +titleLen:[* TO
MAX_LEN]" - but I don't know how to retrive the MAX_LEN information for a
specific query, since it depends in some cases of what an analyzer-chain
will be used at the tokenLen-field.
For example: I think it makes sense to use a WordDelimiterFilter at the end
of my TokenFilter-chain.
If my document is something like "The secrets of the iPhone 3G", than I want
to index it as "The secrets of the iPhone 3 G" (3G is going to be indexed as
two tokens).
This means, that the document length is increased by one token.
However, maybe I missunderstood your point:
"- Pick MAX_LEN Based On Number Of Query Clauses From Super"
since I thought, that the number of query clauses depends on the number of
whitespaces in my query. If I am wrong, and it depends on the result of my
analyzer-chain, there is no problem. But I am not sure, if this is the case
or not.
Thank you for help.
