SEARCH TEXT FIELD
Type a word or entry name into this field, and then click SEARCH or press  the <return> key.
If the SEARCH OPTIONS button says WORD... 
    Starts a search for any entries containing that word. You can search for most nouns and proper names. These are single-word searches only, so if you are looking for a multi-word phrase, try the most unique word of that phrase.
If the SEARCH OPTIONS button says ENTRY... 
    The index will automatically jump to a location  which most closely matches what you have typed. This automatic search is case-sensitive and will occur any time you have paused after typing the first few letters of an entry.
