order of parameters and OR symbol.

[hhtt]

I have folder called sn. Under it I have files and folders with their name including X, Y, Z. Some includes X and Y in their name or some only with X or Y but under that folders with X and Y there again folder names with X and Y. Actually the situation is very easy.

X sn | Y sn | Z sn gives a different result than sn X | Y sn | Z sn. This seems strange to me. Would you please explain it? But we know that order of parameters are no important in everything. So both should have given the result " all folders under sn (because X, Y and Z under sn) X, Y, Z.

What is wrong?

Thank you.

Please try with <>
<X sn> | <Y sn> | <Z sn>

(space is AND, | is OR)

I checked the operator precedence and see that there are two options. I don't know how these options take effect? Would you please explain these options? I will also try to understand them by changing them so that I could have an idea by the differences. Meanwhile is there any document or link other than FAQ which explains some options? And we also forgot to mention "match case" option. When I did that search "match case" was enabled. I always enable "match case".

Thank you.

123 456|789
123 AND 456 OR 789
can be interpreted as:
<123 AND 456> OR <789>
or
<123> AND <456 OR 789>

I always enable "match case".

Look at stauts bar, for "match case" indicator.
Also, if you want "match case" to be enabled always, you should edit HOME tab in Options:
Menu: Tools > Options > Home
