The search itself. The first argument - session, the next one -
|
|
query itself. To find something just type words you want to find
|
|
and press SUBMIT button. For example, "mysql odbc". You should
|
|
not use quotes " in query, they are written here only to divide a
|
|
query from other text. mnoGoSearch will find all documents that
|
|
contain word "mysql" and/or word "odbc". Best documents having
|
|
bigger weights will be displayed first. If you use search mode
|
|
ALL, search will return documents that contain both (or more)
|
|
words you entered. In case you use mode ANY, the search will
|
|
return list of documents that contain any of the words you
|
|
entered. If you want more advanced results you may use query
|
|
language. You should select "bool" match mode in the search
|
|
from.

mnoGoSearch understands the following boolean operators:
|
|
</simpara>
|
|
|
|
<simpara>
|
|
& - logical AND. For example, "mysql &
|
|
odbc". mnoGoSearch will find any URLs that contain both
|
|
"mysql" and "odbc".
|
|
</simpara>
|
|
<simpara>
|
|
| - logical OR. For example "mysql|odbc". mnoGoSearch
|
|
will find any URLs, that contain word "mysql" or word
|
|
"odbc".
|
|
</simpara>
|
|
<simpara>
|
|
~ - logical NOT. For example "mysql & ~odbc".
|
|
mnoGoSearch will find URLs that contain word "mysql"
|
|
and do not contain word "odbc" at the same time. Note
|
|
that ~ just excludes given word from results. Query
|
|
"~odbc" will find nothing!
|
|
</simpara>
|
|
<simpara>
|
|
() - group command to compose more complex queries. For example
|
|
"(mysql | msql) & ~postgres". Query language is
|
|
simple and powerful at the same time. Just consider query as
|
|
usual boolean expression.
