Thanks for this recommendation. I'm using pgweb as a general purpose SQL web interface to Postgres. But, I cannot easily adapt pgweb to bring out a search interface that only searches a certain column of table in postgres.
Not sure what kind of issues you're having with search, but it's pretty straightforward to browse table data with a filter on a single column (be it numerical or text data). Im the author - shoot me an email (in profile) if you have any questions.
