path

path

Index files path and file name (without extension). Mandatory.

Path specifies both directory and file name, but without extension. indexer will append different extensions to this path when generating final names for both permanent and temporary index files. Permanent data files have several different extensions starting with '.sp'; temporary files' extensions start with '.tmp'. It's safe to remove .tmp* files is if indexer fails to remove them automatically.

For reference, different index files store the following data:

  • .spa stores document attributes (used in extern docinfo storage mode only);
  • .spd stores matching document ID lists for each word ID;
  • .sph stores index header information;
  • .spi stores word lists (word IDs and pointers to .spd file);
  • .spk stores kill-lists;
  • .spm stores MVA data;
  • .spp stores hit (aka posting, aka word occurrence) lists for each word ID;
  • .sps stores string attribute data.
  • .spe stores skip-lists to speed up doc-list filtering

Example:

path = /var/data/test1
