Don't forget to test your field type analyzers on the Solr Admin "analysis"
page. It will show you exactly how terms gets analyzed at both index and
query time.
If something is not working, be specific as to what the case is and exactly
what is not as you would expect, both the expected value and the actual
value.

You need to apply the edge n-gram filter only at index time, not at query
time. So, you need to specify two analyzers for these field types, an
"index" and a "query" analyzer. They should be roughly the same, but the
"query" analyzer would not have the edge n-gram filter since you are
accepting the single n-gram given by the user and then matching it against
the full list of n-grams that are in the index.
It is unfortunate that the wiki example is misleading. Just as bad, we
don't have an example in the example schema.
Basically, take a "text" field type that you like from the Solr example
schema and then add the edge n-gram filter to its "index" analyzer,
probably as the last token filter. I would note that the edge n-gram
filter
will interact with the stemming filter, but there is not much you can do
other than try different stemmers and experiment with whether stemming
should be before or after the edge n-gram filter. I suspect that having
stemming after edge n-gram may be better.

All,
I am using apache-solr-4.0.0-ALPHA and trying to configure the Partial
search on two fields.
Keywords using to search are
The value inside the search ProdSymbl is M1.6X0.35 9P
and I willl have to get the results if I search for M1.6 or X0.35
(Partial
of the search value).
I have tried using both NGramTokenizerFactory and
solr.EdgeNGramFilterFactory
in the schema.xml
<!-- bigram -->
<!-- <fieldType name="bigram"
class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.**NGramTokenizerFactory" minGramSize="3"
maxGramSize="15" />
<filter class="solr.**LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.**WhitespaceTokenizerFactory" />
<filter class="solr.**LowerCaseFilterFactory"/>
</analyzer>
</fieldType> -->
<fieldType name="bigram" class="solr.TextField"
omitNorms="false">
<analyzer>
<tokenizer class="solr.**StandardTokenizerFactory"/>
<filter class="solr.**StandardFilterFactory"/>
<filter class="solr.**LowerCaseFilterFactory"/>
<filter class="solr.**EdgeNGramFilterFactory" minGramSize="2"
maxGramSize="15" side="front"/>
</analyzer>
</fieldType>
Fields I have configured as
<field name="prodsymbl" type="bigraml" indexed="true" stored="true"
multiValued="true"/>
<field name="measure1" type="bigram" indexed="true" stored="true"
multiValued="true"/>
Copy field as
<copyField source="prodsymbl" dest="text"/>
<copyField source="measure1" dest="text"/>
Please let me know IF I and missing anything, this is kind of Urgent
requirement needs to be addressed at the earliest, Please help.
Thanks in advance,
