For the MQL4.community, we created a new search engine that can search in different
sections:
It is a beta version yet, and we are improving it now. The search form can be found
at the top right of each page.
Use instructions are very simple and resemble those of standard search engines:
In the search term box, several key words can be entered. They must be separated
by spaces, for example: test metaquotes, the engine cannot search for complete phrases, only words.
The following logical operators can be used in requests:
space or & or and – Logical AND
At the request, all messages that contain all key words combined by this operator
will be found.
| or or – Logical OR
At the request, all messages that contain at least one of key words combined by
this operator will be found.
! or not – Logical NOT
This applies to one key word. At the request, all messages that do not contain
this key word will be found.
( ) – Round brackets
order logical operators.
Example: ((expert | test) & genetic) !metaquotes – search for messages that contain expert and genetic, or test and genetic, but not metaquotes.
The search considers grammatical form of key words. For example, it will not be
able to find messages that contain the word duplicate at the request for duplication. So, for search to scope maximum messages, please specify incomplete key word,
for example, without ending (like duplicat for the above example).
If you need to find an exact word that would not be a part of another word, just
quote it. Thus, for example, for the key word of "intercept", there will not be any results containing interception or intercepted.
Search for message texts ignores the following:
key words consisting of only one character
key words that contain letters not included into the standard alphabet
