Boolean expression settings are used to control how the operators LIKE and NEAR behave.
LIKE Sensitivity
The LIKE operator can be configured for different sensitivity when matching search terms to similar words. The possible settings are:
Very similar |
Only slight differences in words are accepted, e.g. a single character out of place. |
Similar |
A wider range of similar words will be matched, e.g. for larger words multiple characters can be out of place. |
Approximate |
Words only need a very approximate similarity to the search term to match. |
NEAR Distance
By default the NEAR operator requires related search terms to be within 100 characters of each other. This can be changed to a user defined limit. The lower the limit then the closer the terms need to be to each other and vice versa.
