Searching can be made easier by selecting either "Full-text" or "Titles only" searching.
Here is how to do it:
1.) When you open content (e.g. Law of New York), select the 'Search' icon in the upper right corner of the screen.
2.) When you search for a particular keyword there, there is an option to search by 'Full-text'.
Or select 'Titles Only'.
Keywords are filtered out when you are searching for particular titles.
