I am using Solr4.2 , I have few queries on new fuzzy implementation in
Solr4+
1) I come to know that Solr4+ accepts maximum editing distance to 2 (2
insertion, deletion, replacements). Is there any way , i can configure this
maximum editing distance limit ??
2) although I set editing distance to 1 in my query (e.g. worde~1), solr
returns me results having 2 editing distance (like WORDOES, WORHEE, WORKEE,
.. ect. )
3) Last and major issue, I had very few data at startup in my solr core (say
around 1K - 2K ), at that time, when i was searching with worde~1 , it was
returning many records (around 450).
Then I ingested few more records in my solr core (say around 1K). It was
ingested successfully , no errors or warning in Log. After that when I
performed the same fuzzy search (worde~1) on previous records only, not in
new ingested records , It did not return me previous results(around 450) as
well, and return total 1 record only having highlight as WORD!N .
It seems like , Issue is causing somewhere while ingesting last 1K records,
but can not able to catch that issue. also solr do not provide any error or
warning in log. Or I don't know the way of debugging this ingestion issue.
Below is configuration for my text field type text_en_splitting.
<fieldType name="text_en_splitting" class="solr.TextField"

Also I have one copy field on this text field , with field type
text_general_preserved. Below is configuration for it.
<fieldType name="text_general_preserved" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<charFilter class="solr.MappingCharFilterFactory"
mapping="mapping-ISOLatin1Accent.txt"/>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords_ns.txt" enablePositionIncrements="false" />
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
<analyzer type="query">
<charFilter class="solr.MappingCharFilterFactory"
mapping="mapping-ISOLatin1Accent.txt"/>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords_extra_query.txt" enablePositionIncrements="false" />
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Hope I explained all my question to be understandable, Please Help me on
This.
