# TG Research Update

The [TG Research](https://blog.telegram.lvivcenter.org/tg-research) platform, a virtual access point to the Archive’s materials, now operates more stably and features a range of new functions.

#### Logical operators

The OR/AND operators in filters no longer return incorrect results. Queries are filtered according to the specified parameters.

#### Time range filter by publication timestamp

You can now limit query results not only by a date range but also by timestamps.
