Perhaps you should try some spelling variations:
"seyedin" » "seyedian", "seyedi", "sewedin", "sayedin"
"serpedin" » "serpin", "eredin"
"seed" » "see", "seen", "seek"
"seyed" » "sewed", "sayed"
"sei" » "seit", "sein", "semi"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((("seyedin" OR "serpedin") OR "seed") OR ("seyed" OR "sei")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"seyedin\" OR \"serpedin\") or \"seed\") or (\"seyed\" or \"sei\"))".
• Removing quotes may allow a broader search: ((( seyedin OR serpedin ) or seed ) or ( seyed or sei )).
• Adding a wildcard symbol may retrieve word variants: ((("seyedin" OR "serpedin") or "seed") or ("seyed" or "sei"))*.
