Both the manual section and description may be zero-length if the record |

Entries are sequentially-numbered, but the filenames are unordered. |
|
.Ss Keyword Database |
|
The keyword database, |

|
is a |

.Xr btree 3 |
|
database of NUL-terminated keywords (record length is non-zero string |
|
length plus one) mapping to a 8-byte binary field consisting of the |
|
keyword type and source |

The last four bytes are a host-ordered record number within the |
|
.Sx Index Database . |
|
.Sh IMPLEMENTATION NOTES |
|
The time to construct a new database pair grows linearly with the |
|
number of keywords in the input files. |
|
However, removing or updating entries with |
|
.Fl u |
|
or |
|
.Fl d , |
|
respectively, grows as a multiple of the index length and input size. |
