Perhaps you should try some spelling variations:
"seyedin" » "serpedin", "seyedn", "seydin", "seyedalin"
"seyedian" » "meredian", "lebedian", "saeedian", "seyedan", "seydian", "seyedalian"
"seyedi" » "seyed", "seydi", "seyedali"
"sedi" » "semi", "sei", "sed"
"seldi" » "selvi"

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 "seyedian") OR "seyedi") OR ("sedi" OR "seldi")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"seyedin\" OR \"seyedian\") or \"seyedi\") or (\"sedi\" or \"seldi\"))".
• Removing quotes may allow a broader search: ((( seyedin OR seyedian ) or seyedi ) or ( sedi or seldi )).
• Adding a wildcard symbol may retrieve word variants: ((("seyedin" OR "seyedian") or "seyedi") or ("sedi" or "seldi"))*.
