[open-humanities] The importance of search

[Sam Leon]

Jonathan, Nick, Laura, Open Humanists,

Really interesting points.

Lack of good search capability on the Internet Archive given the
unreliability of its OCR scans was something I sorely missed during my
dissertation.

As Nick says much of the very useful searches we want to do will be trivial
to implement. the fact is I've never seen any platform that allows you to
search for a given word across the whole body of an authors work.

>From a UI perspective it would be good to nail down the kind of searches
people will be wanting to do with TEXTS so that we can give them an
interface that matches that - something for the next user requirements
workshop!

@Jonathan - could you add the kind of search that you were talking about to
the user stories on the Wiki please?
