Tendermint version (use tendermint version or git rev-parse --verify HEAD if installed from source):

Environment: LotionJS

• OS (e.g. from /etc/os-release): Linux
• Install tools: npm

What happened:

Issuing a query with an inequality comparison for tx.height results in a string comparison. Specific example is the following query:

tx_search?query="event='value' AND tx.height>=15"

results in matches:

15, 15545, 15555, 151808...

and the following query

tx_search?query="event='value' AND tx.height<100000"

returns an empty array []

What this means is that every attempt to query for tags within a range (which by definition includes a > and < operator) will return an empty array.

What you expected to happen:

tx.height should be compared as an integer so tags can be queried in a range of blocks. It appears that tx.height is stored as a string in the transaction which is perhaps the underlying problem:

{
        "hash": "75B0775C6003225B456F1975817DADB97B00F90A",
        "height": "154248",
        "index": 0,
...
}
