Basic filters (WHERE)

[Seddryck]

It should be possible to filter the result of a query based on

Facets

• [X] Equal
• [X] Not equal
• [X] In

Measurement

• [X] Culler (removing rows where the measurement is not equal, greater or less than a static value)

Timestamp

• [X] After (select rows if they are after a given timestamp)
• [X] Before (select rows if they are before a given timestamp)
• [X] Between (select rows if they are between two timestamps)
• [X] Since (select rows if they are in an interval ending now and with a duration specified by an interval)

We should also impelment a dictionary for the comparison operators (=, <>, >= ...)
