When mnoGoSearch is used with ispell support all words are normalized by both indexer and search front-end. It allows to find
same words with different endings. For example, if words "testing" or "tests" are found in a document, the word "test" will
be stored by indexer instead. Search front-end will also try to find the word "test" if "testing" or "tests" is given in search
query. Note that this scheme lacks exact search possibility, but usually reduces database size and makes search faster.
If you add ispell support to already existing database, reindexing is required. In other case non-normalized words will not
be found at all.
Two types of ispell files
MnoGoSearch understands two types of ispell files: affixes and dictionaries. Ispell affixes file contains rules for words
and has approximately the following format:
Table 15.1. Flag V:
| E |
> -E, IVE |
As in create > creative |
| [^E] |
> IVE |
As in prevent > preventive |
Table 15.2. Flag *N:
| E |
> -E, ION |
As in create > creation |
| Y |
> -Y, ICATION |
As in multiply > multiplication |
| [^EY] |
> EN |
As in fall > fallen |
Ispell dictionary file contains words themselves and has the following format:
Table 15.3.
| wop/S |
| word/DGJMS |
| wordage/S |
| wordbook |
| wordily |
| wordless/P |
