Can not find accepted photos in search

Hello,

Although I have the keywords written, both in keywords place and title, some of my photos do not come up when searched.

Example:

I can see my photos of "Siena", an Italian city in my portfolio.

All these photos have the keyword "Siena" in keywords (first place!) and titles

But they do not come up in my own portfolio results. Other irrelevant photos come up. Some photos do, but some do not. Siena is just an example, I have photos showing up and photos not. I am a bit confused.

So I can not make a check if everything is OK or not - are they really in my portfolio or are they lost.

Anyone has any ideas, or same experience?

Thank you,

CanY.
