Bug: Wrong metadata filter

[amindadgar]

the Metadata filter that we're doing, an OR operation is applied between thread names, channel names and days, So this does mean we can get data from other channels, threads, or days and not just the threads, channels, and days we want.
Reviewing the llama-index library it seems that, it is not possible to combine AND and OR statements and we can only apply a condition (AND or OR) between many ExactMatchFilters.
We need to come up with a solution to either query the data ourselves or add another feature to llama-index library to be able to do combination of filters.
