Article Anywhere is really great in returning a huge collection of Articles, paginated and displayed in my desired Grid/Column layout format!
Now I am looking for a kind of search box option (on [title]), so visitors can zoom in those returned Article Anywhere results, by using their custom search word(s). After hitting this desired search button, (somewhere beside the pagination tabs) they should only keep the matching results of that in the same Grid/Columb layout format.
There is no built-in search box functionality in Articles Anywhere.
You could create your own form and pass the search string to the {articles} tag. But that will only do the search in the given data type (title / introtext / fulltext / ...) and not on all possible things you want to search in.
There is no search component integrated into Articles Anywhere.
You can use a search component that indexes the pages/content, so that the output of the plugins (like Articles Anywhere) is indexed.
