'Searches' in the Bible

“As for you, Solomon my son, know the God of your father, and serve Him with a whole heart and a willing mind, for the Lord searches every heart and understands the intention of every thought. If you seek Him, He will be found by you, but if you forsake Him, He will reject you forever.

From there it searches for prey;its eyes penetrate the distance.

The one who searches for what is good finds favor,but if someone looks for trouble, it will come to him.

which my soul continually searches for but does not find: among a thousand people I have found one true man, but among all these I have not found a true woman.
