I have a large key-value database of words. Each entry is a word that replaces another word. I am given a continuous stream of text where I have to replace the words with corresponding words in the database.

For example when I want to cache web pages I use a caching reverse proxy such as varnish. When I want text indexing, I use an indexing service such as apache solr. They can be used as dedicated services that are good at what they do.

Are there any server softwares that can do such text processing/replacement efficiently?
