  SteelArrow for Fuzzy Searching    
 
   

With the new phonetic and fuzziness functions, it is now possible to use SteelArrow for "fuzzy" searching. This demo uses a database of given names, and a very small script to demonstrate the functionality.

The script to retrieve the data is as follows;

 <!--- Get the phonetic sound of the name --->
 <SASET NAME=phName VALUE=Phonetic( PARAM.name )>

 <!--- Compare against the values in the database --->
 <SAQUERY NAME=results DATASOURCE="Phonetic">
   SELECT * FROM Phonetic WHERE key = '#phName#'
 </SAQUERY>

 <SAIF COND=results.RowCount()>
   <!--- Iterate over the database results --->
   <SAWHILE COND=results.MoreData()>
     <!--- Get "fuzziness" of database word to supplied word --->
     <SASET NAME=results.fuzzy[] 
          VALUE=Fuzziness(tolower(PARAM.name),tolower(results.word))>
     <SANEXT NAME=results>
   </SAWHILE>
   <SAFIRST NAME=results>
   <SASET NAME=results VALUE=results.Sort("fuzzy" )>
 </SAIF>
