Yesterday we implemented an improved search system, Lucene.
It allows us to search in many different ways, but the most important ones for us are the term and field seraches.
Terms can be single (just one word like "English") or phrases (a group of words in qutoes "learn English"). The field search allows us to be more specific and lets us search by title and text. For example I want to only search a word or phrase that is in the title ONLY, I will write in the search box title:"English Language"
We can also search by tags, username and include the date and change how it is sorted.
