The behavior you describe is exactly as FileMaker finds are supposed to work.
Learn how to use find operators if you want to make finds behave differently.
but the user just types "A" in a search field.
So, if the users only type an A and you want other than the default behavior, you have two choices:
1. User training. Teach the user how searches work,
2. Create a custom Search interface where you take the search term the user enters ("A", for example) and modify that entry and do the actual search yourself behind the scenes.
You said "I want he can see all names have A." A where? as the first char in the field? anywhere in the field? somewhere specific in the field?
A at the first of all names, Like:
And my search field is global!
create a calculated field that extracts the first character of the name field and find on that
So, to see all the names with "A" anywhere in the text, you could take what the user enters, an "A", and behind the scenes do a Find after adding wild-card characters with "*A*"
Spend a little time experimenting yourself:
1. Open FileMaker,
2. Click Find,
3. Click the Operators button at the top and experiment with these:
What exactly do you mean by "mark it"?
Precise questions = accurate answers.
Once again you want us to do the work for you.
And make sure you put in a few more !!!! and capitalizations... it really gets our attention
because this option available only for index fields I think you gave
another way to do this work
