binary search

Hi,

 

I am having problems with fast binary search.

 

Whenever you search for company symbol "T" (AT&T), search engine returns all records for "T" as well as "T.AAA", "T.BOL", etc.

 

http://www1.zacks.com/cgi-bin/reports_store/scan/st=text/fi=dict.ticker/df=yes/di=-1/rf=1/ml=10/dl=T

 

here is a piece from index file (dict.ticker) :

T       N0122046
T       N0121292
T       N0119307
T       N0119482
T       N0118346
T       N0121054
T       N0111370
T       N0115402
T       N0105209
T.AAA   N0133024
T.AC    F0097374
T.ACE   F0095185
T.AP    N0148013
T.ASY   N0138216
T.ASY   N0131468
T.ATD   F0098075
T.ATY   N0134675
T.AUR   N0131289
T.BCX   N0134868
T.BOL   N0136623

here is the search form code:

 

        <FORM METHOD=POST ACTION="[process-target none]">
                <INPUT TYPE=hidden NAME=mv_searchtype VALUE="text">
                <INPUT TYPE=hidden NAME=mv_search_file VALUE="dict.ticker">
               <font size=-1 face="arial, helvetica, san-serif"><B>Enter New Ticker</B></font><br>
                <INPUT  NAME="mv_dict_look" size=6 >
                 <INPUT  TYPE=hidden NAME="mv_dict_fold" VALUE="yes">
                <INPUT TYPE=hidden NAME=mv_dict_limit VALUE="-1">
                <INPUT TYPE=hidden NAME=mv_return_fields VALUE=1>
                <INPUT TYPE="hidden" NAME="mv_matchlimit" VALUE="10">
                <INPUT TYPE="submit" NAME="mv_todo" VALUE="Search">
                <INPUT TYPE="hidden" NAME="mv_doit" VALUE="search">

 

        </FORM>

Any recommendations?

 

regards
