i am using the following filter

"name\_ngrams":{  
"side":"front",  
"max\_gram":50,  
"min\_gram":2,  
"type":"edgeNGram"  
},  
"name\_ngrams\_back":{  
"side":"back",  
"max\_gram":50,  
"min\_gram":2,  
"type":"edgeNGram"  
},  
"name\_middle\_ngrams":{  
"type":"nGram",  
"max\_gram":50,  
"min\_gram":2  
},

for the index

an i am not using these filters for the search query for some reason when i  
search

\*technolgy \*no result crop up

yet when i search for _technology, technologic, technolo_, results do apear  
anyone might explain why this is happening?

Ok i think i understand why since the anaylser i m using for the search  
query requires an exact match not a partial match.
