Question

I have SQL rows with this information:
Example – Exampleish (Exampleishbosh)

not all have () in them, so would it be a good idea to strip the

- and ()

out of the url and then just do a search with the remaining words in the SQL query?

http://www.co.com/example_exampleish_exampleishbosh/

or is this a bad idea?

Answer 1

Since the question is a bit unclear to me, I’m assuming that the information string acts as a key-sort-of-thing for additional information (like a title for an article), and there is no true GET search requirement.

If this is the case, if allowed to modify the database structure, I would use some kind of surrogate key instead (like a numeric identifier), using the title-thingy as a slug.

In this case, your when generating links in your website, you get both the id and slug for the target, and create an url of it in the format http://example.com/[id]/[slug]/, for example http://example.com/213/omg-lol-the-cat-jumped/.

When processing the request in your server, you are only interested in the id (“213”), and the slug (“omg-lol-the-cat-jumped”) is just for the human user to give a sneak-peek of the title, and doesn’t affect the search result. You provide the page that matches the id, not the slug. This way, your searching is efficient (no SQL LIKE-matching), and less error prone (SQL injections from malformatted slugs).

As for the (possible?) question about how to convert a string into a slug, there are many approaches to that. I would simply remove all non-alphanumeric characters, and combine the alphanumeric chunks with dashes or underscores. You probably want to cut the string length to 20-ish characters.
