.SH OPERATIONAL NOTES
.PP
The SQLite3 database file is stored in:
  - \fI$XDG_DATA_HOME/buku/bookmarks.db\fR, if XDG_DATA_HOME is defined (first preference) or
  - \fI$HOME/.local/share/buku/bookmarks.db\fR, if HOME is defined (second preference) or
  - the \fIcurrent directory\fR.
.PP
It's advisable to copy URLs directly from the browser address bar, i.e., along with the leading 'http://' or 'https://' token. buku looks up title data (found within <title></title> tags of HTML) from the web ONLY for fully-formed HTTP(S) URLs.
.PP
If the URL contains characters like ';', '&' or brackets they may be interpreted specially by the shell. To avoid it, add the URL within single or double quotes ('/").
.PP
URLs are unique in DB. The same URL cannot be added twice.
.PP
\fITags\fR:
  - Comma (',') is the tag delimiter in DB. A tag cannot have comma(s) in it. Tags are filtered (for unique tags) and sorted. Tags can be replaced.
.PP
\fIDelete\fR operation:
  - When a record is deleted, the last record is moved to the index.
  - Delete doesn't work with range and indices provided together as arguments. It's an intentional decision to avoid extra sorting, in-range checks and to keep the auto-DB compaction functionality intact. On the same lines, indices are deleted in descending order.
  - Can delete bookmarks matching a search, when combined with any of the search options.
.PP
\fIUpdate\fR operation:
  - If --title, --tag or --comment is passed without argument, clear the corresponding field from DB.
  - If --url is passed (and --title is omitted), update the title from web using the URL.
  - If indices are passed without any other options (--url, --title, --tag and --comment), read the URLs from DB and update titles from web.
.PP
\fISearch\fR works in mysterious ways:
  - Case-insensitive.
  - Matches exact words in URL, title and tags.
  - --sany : match any of the keywords in URL, title or tags.
  - --sall : match all the keywords in URL, title or tags.
  - --deep : match \fBsubstrings\fR (`match` matches `rematched`) in URL, title and tags.
  - --sreg : match a regular expression (ignores --deep).
  - --stag : search bookmarks by tag, or show all tags alphabetically.
  - Search results are indexed serially. This index is different from actual database index of a bookmark record which is shown in bold within '[]' after the URL.
.PP
\fIEncryption\fR is optional and manual. AES256 algorithm is used. To use encryption, the database file should be unlocked (-k) before using buku and locked (-l) afterwards. Between these 2 operations, the database file lies unencrypted on the disk, and NOT in memory. Also, note that the database file is \fBunencrypted on creation\fR.
