Member Function Documentation

void org.net2map.pov.server.DimensionSubsetWord.buildSubset (   )  [virtual]
 

Build query using expression to define subset of database elements.

crc32 mode uses specials tables and fields

Words are extracted from query string to build WordList object

Every words are checked...

...They are deleted from WordList if they are declared as stopword...

...Else they are normalized

A WordList is build and contains every word and word linked to

For every words...

A temporary table may be used...

The current word will be found in table dict
