(1) mandb:
|
|
This is the main FTS table which contains all the content from
|
|
man pages
|
|
|
|
COLUMN NAME DESCRIPTION
|
|
1. section Section number of the page
|
|
2. name The name of the page
|
|
3. name_desc The one line description from the NAME section
|
|
4. desc Contains the content from DESCRIPTION
|
|
section and any other section which
|
|

12. md5_hash md5 hash of the man page (UNIQUE)
|
|
13. machine The machine architecture (if any) for which this page is
|
|
relevant.
|
|
|
|
(2) mandb_meta:
|
|
This table contains md5 hashes of all the indexed man
|
|
pages. This is there to make sure we do not index
|
|
the same man page twice, i.e. to prevent indexing
|
|
hardlinks.
|
|
|
|
COLUMN NAME DESCRIPTION
|
|
1. device (dev_t)Logical device number from stat(2)
|
|
2. inode (ino_t)Inode number from stat(2)

|
|
5. md5_hash MD5 Hash of the man page (UNIQUE)
|
|
6. id A unique integer ID for the page, which
|
|
refers to the docid column in mandb (Implicit foreign
|
|
key?) PRIMARY KEY
|
|
{device, inode} form a UNIQUE index
|
|
|
|
(3) mandb_links:
|
|
This is an index of all the hard/soft links of the man
|
|
pages. The list of the linked pages is usually obtained
|
|
from the multiple .Nm entries in the page.
