Compare strings with non-English characters?

Question

I need to compare strings for a search mechanism on a web site. I use C#. I tried two ways:

consultants.Where(x => 
    x.Description.ToLower().Contains(v

Indexing is a big part of searching. I think you would be best served by using something ready and solid, like Lucene or Solr.

If you still insist on searching using regexes on non-ascii characters, you should probably learn more on unicode categories and then use them to strip any accent marks (for example, strip with \p{P} or \p{M}) before searching for that word in the text.

Note: You will also probably need to normalize your strings using the FormC flag in order to decompose and strip/search more effectively
