This page aims to compare the possibilities and limitations of search functions using [[toolkit:pogrep]] and indexing features.

| ^ pogrep ^ indexing ^
^ Regular expressions | ✔ | ✘ |
^ Fields (source, target, etc.) | ✔ | ✔ |
^ Case-sensitivity | ✔ | ✘ (always case insensitive) |
^ Unicode normalisation | ✔ (auto) | ✔ (auto) |
^ Recursive | ✔ (auto) | ✔ (maybe needs changes in Pootle) |

===== Comments =====

==== Regular expressions ====
The indexing engines can match the following:
  * single words (complete or incomplete; the start must always match)
  * multiple words
  * regular expressions are not supported


==== Recursive ====
The filename of each string is indexed, thus the indexing code supports file based filtering. Pootle with pogrep can work automatically on a subdirectory of a project.
