Recoll index format details

Special (capitalized) terms:

• Ddate: modification date of file, like YYYYMMDD
• Mmonth: YYYYMM
• Ppathhash truncated/hashed version of file path. For single-document files, and for the file part of a multi-document file. Used for up-to-date checks and for retrieving a document by path. omega uses U for the equivalent term used for up to date checks.
• Qpathhash+ipath same + internal path for documents inside multi-document files. Used to set the existence flag for subdocs when a multi-document file is found to be up to date, or for deleting all subdocs for a file, or for retrieving a document by path+ipath. No real omega equivalent. Compatible with Q definition in termprefixes.txt: unique identifier.
• Tmimetype: document mime type.
• Wweak: 10 days period (not used any more by omega)
• Yyear YYYY
• XSFNfilename utf8 version of file name. Used for specific file name searches
