'Search' in the Bible

I made a search with my heart to give pleasure to my flesh with wine, still guiding my heart with wisdom, and to go after foolish things, so that I might see what was good for the sons of men to do under the heavens all the days of their life.

And I went again in search of wisdom and of foolish ways. What may the man do who comes after the king? The thing which he has done before.

A time for search and a time for loss; a time to keep and a time to give away;

Whatever is has been before, and what is to be is now; because God makes search for the things which are past.

Then I saw all the work of God, and that man may not get knowledge of the work which is done under the sun; because, if a man gives hard work to the search he will not get knowledge, and even if the wise man seems to be coming to the end of his search, still he will be without knowledge.

The Preacher made search for words which were pleasing, but his writing was in words upright and true.
