Baloo offers a rich syntax for searching through your files. Certain attributes of a file can be searched through.

For example 'type' can be used to filter for files based on their general type:

  type:Audio or type:Document

The following comparison operators are supported, but note that 'not equal' operator is not available.
  · :   - contains (only for text comparison)
  · =   - equal
  · >   - greater than
  · >=  - greater than or equal to
  · <   - less than
  · <=  - less than or equal to

Currently the following types are supported:

  · Archive
  · Folder
  · Audio
  · Video
  · Image
  · Document
    · Spreadsheet
    · Presentation
  · Text

These expressions can be combined using AND or OR and additional parenthesis, but note that 'NOT' logical operator is not available.

[... omitted for brevity, but includes the full list of searchable properties as in your original script ...]

{PROG_NAME} recognizes some natural language sentences in English, as long as they are capitalized, and transforms them into queries that can be interpreted by the search engine.

Supported natural language sentences and patterns for queries are:
  · MODIFIED TODAY
  · MODIFIED YESTERDAY
  · MODIFIED THIS [ DAY | WEEK | MONTH | YEAR ]
  · LAST <NUMBER> [ DAYS | WEEKS | MONTHS | YEARS ]
  · <NUMBER> [ DAYS | WEEKS | MONTHS | YEARS ] AGO

<NUMBER> can be any number or a number text from ONE to TWENTY.

Remarks: LAST DAY, if used, is interpreted as YESTERDAY.

Supported expressions for --exclude and --recursive-exclude are:
  · width<CMP_OP>height  - only if file has width and height properties
  · height<CMP_OP>width  - only if file has width and height properties
  · PORTRAIT             - only if file width is greater or equal to height
  · LANDSCAPE            - only if file height is greater or equal to width
  · SQUARE               - only if file width equals to height

<CMP_OP> can be: != | >= | <= | = | > | <"""
