In this chapter:
We tried our hand at a practical application that uses a Sphinx backend to perform the core task of searching
We used PHP for creating an application that fetches different feeds and stores the feed item data in a Sphinx index
We created a search form that acts as the frontend for searching.
We learned how to create indexes in the main+delta scheme and how to re-index
In the next chapter we will take up another practical application that will involve some advance features of Sphinx.
