# Suggestion Improve database search?

Hello,

May I suggest an improvement to the forum: provide more advance techniques to search. For example, suppose I wanted to find out everything regarding convergence of the following integral:

$$\int_0^{1/2}\frac{x^{a-1}}{\ln(x)}dx$$

Over 2 million entries seems like such a wonderful database of math. However obtaining the information seems to be difficult.

Is is possible to write a db search engine and input: "convergence of \int_0^{1/2}\frac{x^{a-1}}{\ln(x)}dx" and have it search not only my string but the integral in general even with different letters and use of log or Log or other limits of integration?
