FullTextSearch

 * The full text search functionality is integrated in modules/s3/s3resource.py, the fulltext() does the work.
-* The flow is: First the TEXT query goes to transform() function, which would split the query recursively and then transform the query.
-* After transforming, the query with TEXT operator will go to fulltext() function and would search for the keywords in the indexed documents.
-* It will retrieve document ids and then covert into a BELONGS S3ResourceQuery.
-* The code sample for the fulltext() is in ''models/s3/s3resource.py''
+* So, The process is:
+First there will be a filter (a new submodule for TextFilter called FullTextFilter) which would generate the query with the TEXT operator.[[BR]]
+Then, The query would do a select() call of the extraction of records with the transform=True parameter.[[BR]]
+Then, in select(), we call the resource.get_query -> rfilter.get_query() -> transform()[[BR]]
+So, in rfilter.get_query, we will transform the TEXT query to a BELONGS S3ResourceQuery by using transform() and fulltext() function[[BR]]
+Note: fulltext() will extract the record ids through Lucene, by giving Lucene the text which the user entered into the filter.[[BR]]
+After generating the BELONGS S3ResourceQuery with the set of ids, we he convert it to a DAL Query.[[BR]]
+So, this is query is returned back to select and a db call for extracting records from this query(filter) will be extracted.[[BR]]
+Finally, we display the records with an extra field into the display which will be the document file field name.

+[[BR]]
+Note: Still left to design the structure for extracting snippets from the query and displaying it along with the records are left.(a @ToDo).[[BR]]
