Arki-query problems in parsing arrays for proddef values

[bchiavarini]

Hi,
we have experienced some problems in queries that use proddef with array values. Here you can find some data where we are experiencing the problem.
When we extract a json summary on these data we obtain proddef values described in this way:

{"items":{...... 
"proddef":[
{
"type":"proddef",
"desc":"GRIB(pl=0,10,0,0, pt=3, tod=8)",
"style":"GRIB",
"value":{"pl":"0,10,0,0","pt":3,"tod":8}}
,....]}}

And when we use the obtained proddef values in a new query like:
arki-query --summary-short --json --annotate "proddef:GRIB:pl=0,10,0,0,pt=3,tod=8" proddef_to_test.grib the result is empty.

Are array values not supported? Is there an alternative way to filter data with these kind of proddef values?

thanks for the help!

Unfortunately, a value that contains commas makes the query syntax ambiguous, and the parser does weird things with it:

$ arki-dump --query 'proddef:GRIB:pl=0,10,0,0,pt=3,tod=8' 
proddef:GRIB:10,0,0,pt=3, pl=0, tod=8

You can remove the ambiguity using double quotes as delimiters for the string value:

$ arki-dump --query 'proddef:GRIB:pl="0,10,0,0",pt=3,tod=8'
proddef:GRIB:pl=0,10,0,0, pt=3, tod=8

arki-dump --query is not well known: it parses a query and reformats it without aliases. It can be useful in some cases to see how arkimet is parsing a query, although indeed something printing out the query in a more structured way would be even more useful.

Does that solve your problem?

I am trying both using
arki-query --summary-short --json --annotate "proddef:GRIB:pl="0,10,0,0",pt=3,tod=8" /arkimet/datasets
or the result of arki-dump --query :
arki-query --summary-short --json --annotate "proddef:GRIB:pl=0,10,0,0, pt=3, tod=8" /arkimet/datasets
but the result is still empty..

btw i didn't know the arki-dump --query command, it can be useful indeed

If this is shell syntax:

I am trying both using arki-query --summary-short --json --annotate "proddef:GRIB:pl="0,10,0,0",pt=3,tod=8" /arkimet/datasets

then you are just closing and reopening the quotes, not quoting them, so the result would be the same as "proddef:GRIB:pl=0,10,0,0,pt=3,tod=8"

sorry, that's true.. i have retried using arki-query --summary-short --json --annotate 'proddef:GRIB:pl="0,10,0,0",pt=3,tod=8' /arkimet/datasets and it works! I can close the issue
Thank you both for the help!
