Hey Uma,

Charfilters should be able to assist you with this.

https://archive.apache.org/dist/lucene/solr/ref-guide/apache-solr-ref-guide-5.5.pdf

solr.PatternReplaceCharFilterFactory or solr.MappingCharFilterFactory depending what you are trying to accomplish. 

As for the extra requirement of doing it at query time, you can simply separate your analyzer into query and index.

For example


<fieldType name="nametext" class="solr.TextField">
  <analyzer type="index">
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.KeepWordFilterFactory" words="keepwords.txt"/>
    <filter class="solr.SynonymFilterFactory" synonyms="syns.txt"/>
  </analyzer>
  <analyzer type="query">
    <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-FoldToASCII.txt"/>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
</fieldType>


Hope this helps


Sid
