Interface:

Database:

Partitions of differenct UUIDs will be stored seperatedly in the database. In circumstances where duplicate UUIDs exist, they will be treated as a single one and records will be overwritten.

  1. Whether search this partition. You need to check it to search the corresponding partition. Icon indicates the mount state.

  2. Can be changed into any name you want. Will display in front of the path when partition unmounted.

  3. Whether update this partition when “Update DB” clicked. You can always update a partition using the context menu, regardless of the checked state.

Menubar:

  1. Edit excluded paths when indexing. Only full path is supported right now. Note: MFT parser will disregard this option.

  2. Check this option to use MFT parser to speed up building index on an NTFS partition (like other MFT based searcher).

  3. Check to use the C++ MFT parser instead of the Python one. The C++ one is supposed to be much faster.

Search Syntax:

Logical Operators Description
  space AND
| vertical bar OR
! exclamation mark NOT
Wildcards Description
  space AND
| vertical bar OR
! exclamation mark NOT

Note: global "nocase" settings DOES have effect on regular expression.
Examples:

reg:"a" will match "123abcd". Will also match "123Abcd" if case-insensitive.
