Perhaps you should try some spelling variations:
"seyedin" » "seyedian", "seyedi", "serpedin", "sewedin", "sayedin"
"seyedn" » "seyedi", "seyede", "seyedian", "sewedn", "sayedn"
"seyen" » "feyen", "leyen", "meyen"
"seyed" » "sewed", "sayed"
"seed" » "see", "seen", "seek"

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