Searching for Symbols in Relativity Continued . . .

April 21, 2020

Here's a follow-up to the Tip of the Night for April 19, 2020

 

After the alphabet file of a dtSearch index is updated, removing a symbol from the ignore subsection and adding it in the Letters section, you can search for many symbols without running a Regex search.   All of these symbols can be directly searched for:

 

$     @     \     /     &     +     ,     .     ;     -     '     `     !     <     >     {     }     ^     _     {     }     |

 

These characters can be searched for with a simplified Regex search that does not reference the unicode value. 

 

?     *     (     )     #    =

 

For example: "##why\?"

 

The unicode value need only be referenced for these characters:

 

"     %     &     :     ~

 

Some  symbols are not part of the ASCII code range.  Two common examples are the UK pound and section symbols: 

£    §

 

A special edit must be made to the alphabet file of a dtSearch index for these symbols.  A new AdditionalLetters subsection must be created and the Unicode value should be listed for each symbol.  

 

It will then be possible to search for these symbols directly.
