10.6 Search View
This agenda view is a general text search facility for Org mode entries. It is particularly useful to find notes.
M-x org-agenda s (org-search-view)
This is a special search that lets you select entries by matching a substring or specific words using a boolean logic.
For example, the search string 'computer equipment' matches entries
that contain 'computer equipment' as a substring.
Search view can also search for specific keywords in the entry, using
Boolean logic. The search string '+computer +wifi -ethernet -{8\.11[bg]}' matches note entries that contain the
keywords 'computer' and 'wifi', but not the keyword 'ethernet', and
which are also not matched by the regular expression '8\.11[bg]',
meaning to exclude both '8.11b' and '8.11g'.
Note that in addition to the agenda files, this command also searches
the files listed in org-agenda-text-search-extra-files.
