Implement "Search Files"

[amourzenkov-sc]

Current behaviour does not allow files/dirs searching.

• Search for files according to file/dir name:

  • [x] File/dir name containing a given substring.
  • [x] Either recursive or not-recursive.
  • [x] Either case-sensitive or case-insensitive.
  • [x] Either dirs, or files, or both files and dirs.
  • [ ] Either skip archives or search in archives.
  • [ ] Allow matching with patterns the shell uses.
  • [ ] Interpret the substing as regular expression.

• Search for files according to file content:

  • [x] File content having a given substring.
  • [ ] Either whole words only or any substring.
  • [ ] Either case-sensitive or case-insensitive.
  • [ ] Interpret the substing as regular expression.

Request query params proposal:

• itemNameSubstring=<string> - file/dir search string, no default.
• itemNameCaseSensitive=[true|false] - false by default.
• itemType=[file|dir] - default is itemType=file&itemType=dir.
• fileContentSubstring=<string> - file content search string, no default.
• recursive=[true|false] - true by default.

[amourzenkov-sc]

Implementation of fileContentSubstring is postponed due to its complexity:

1. Node.js streams for any file size handling.
2. Mechanism of differentiation between binary and text files.
3. Utility for reading a content of pdf/doc/odc/... files.
