If you want to find one of 10k items in a large file, there's no straight, easy way to avoid comparing each item against each line in file. What you can do is
break when found.
You could try a
binary search algorithm.

DWWW(1) Debian DWWW(1)
NAME
dwww - access documentation via WWW
SYNOPSIS
http://localhost/dwww/index.html
dwww
dwww program-name | package-name
DESCRIPTION
A typical Linux system has documentation in many formats (manual pages, info files, READMEs, and so on). dwww makes it possible to access
all of these via the same interface, a WWW browser. This makes it easier to use the documentation.
To use dwww, load the URL given in the SYNOPSIS. If you have a web browser installed, you can also just run the dwww command which loads
the URL. If BROWSER environment variable is set, dwww uses sensible-browser(1) to load the URL. Otherwise, dwww first tries to use
browser specified by DWWW_BROWSER or DWWW_X11_BROWSER configuration variable (cf. dwww(7)), than will use sensible-browser(1) command.
If optional argument program-name or package-name is specified, dwww will search all documentation related to given program or package.
ENVIRONMENT
BROWSER
Program used to load the above mentioned URL.
FILES
/etc/dwww/dwww.conf
Configuration file for dwww.
SEE ALSO
dwww-find(8), dwww(7), sensible-browser(1).
