reference url above:
i’m working with a large catalog of items, about 10,000 and wish to implement a search engine.
i am utilizing the catablog plugin which uses shortcode to implement it’s data.
http://catablog.illproductions.com/
everything works okay when searching by key words of the section such as “garden” “wood” or “accent” but what the client has requested is to be able to search by number as well as key words. in the catalog, the item titles are numbers not words. for example “67010″.
when i search any of the catalog item numbers (item title) i get zero search results.
any help would be greatly appreciated!
thank you,
lani
