DoubleCommanderQSF

This is modification of quick search/filter (QSF) inside DC

The proposed changes adds AND operator (in examples defined with a " " (a space)) for QSF and enables use of activation characters for enhanced behaviour (see pictures). Pictures demonstrate functionality using a filter, which provides better visual feedback.

In the example pictures below there the characters define following behaviour:

Activation character	Behaviour	Example
!	negative mask	Fig. 2
>	mask from template or category	Fig. 3
/	consecutive character matching	Fig. 4
\	regular expression	Fig. 5
<	similarity search	-

Currently, the QSF lacks an AND operator, which makes it difficult to search for filenames in a random order. By adding this functionality, users can create more complex queries and achieve more precise filtering. Fig 1.: AND operator left, Native QSF right to acompolish same result

Change functionality using activation characters. Some characters are not allowed in filenames eg. "/" (slashes) so writing those in QSF field will result in no match (empty panel for filter). This "functionality", which distinguises mask from template is already present in unit uSearchTemplate, where the cTemplateSign = '>'; is used to determine if string is template or mask.

Addition of this functionality: Negative result for QSF: (Sometimes is easier to define mask for undesired results to hide) Fig 2.: Hide folders/files.

Template (+color category mask) for QSF: Fig 3.: Use predefined (color) mask or templates.

Consecutive/adjacent character matching: Fig 4.: Consecutive character matching, Native QSF behaviour right to acompolish same result

RegularExpression (allows for brackets + semi-complex searches), however it is case sensitive. Fig 5.: RegEx example with a "|" allowing all combinations with mask.
