Hi Guys,
It is somewhat difficult to suggest something useful without more
details. If you a pretty sure of the quality of the query, then here is my
suggestion:
Index the documents with an extra field called "last_word" that will
contains the last word in the document. So from your example below :
Document 1: content=ELECTRONICS DIGITAL CAMERA, last_word=CAMERA
Document 2: content=ELECTRONICS DIGITAL CAMERA BATTERY ACCESSORIES,
last_word=ACCESSORIES
Document 3: content=ELECTRONICS DIGITAL CAMERA 0PTICS,last_word=OPTICS
Document 4: content=ELECTRONICS DIGITAL CAMERA
ACCESSORIES,last_words=ACCESSORIES
Document 5: content=ELECTRONICS DIGITAL CAMERA CABEL
ACCESSORIES,last_words=ACCESSORIES
Document 6: content=ELECTRONICS DIGITAL CAMERA OPTICS CABEL
ACCESSORIES,last_words=ACCESSORIES
Document 7: content=ELECTRONICS DIGITAL CAMERA APPERAL
ACCESSORIES,last_words=ACCESSORIES
Then, when the query looks like: "Digital Camera Optics", you can rewrite
the query: "digital camera optics +last_word:optics"
If this query returned nothing, then search without the term
last_word:optics and sort the results by score and be length...
Does that help ?
Jp

Any other Ideas , Please advise....

You can ask the user to provide mandatory terms and optional terms and
then combine the queries in a
mandatory : digital camera optics
optional: battery cable
an then create the query: +digital +camera +optics battery cable
Hope it helps even if I don't know if I undestood your problem correctly.
