 A transaction is a set of log lines that belongs together, e.g. a
-client request. The API monitors the log, and collects all log records
-that make up a transaction before reporting on that
-transaction. Transactions can also be grouped, meaning backend

 transactions are reported together with the client transaction that
 initiated it.
 
 A query is run on a group of transactions. A query expression is true
 if there is a log record within the group that satisfies the
-condition. It is false only if none of the log records satisfied the
+condition. It is false only if none of the log records satisfies the
 condition. Query expressions can be combined using boolean functions.
 
 GROUPING
 ========
 
 When grouping transactions, there is a hierarchy structure showing
-which transaction initiated what. The level increases by one by a
+which transaction initiated what. The level increases by one by an
 'initiated by' relation, so for example a backend transaction will
 have one higher level than the client transaction that initiated it on
 a cache miss. Levels start counting at 1, except when using raw where
