datetime filter does not work as specified?

[drzhouq]

number of landsat8 scene since 2018-01-01 is 684, but 558 since 2017-01-01. What did I do wrong? or there is a bug?

curl "https://sat-api.developmentseed.org/search/stac" -d '{"collection":"landsat-8",  "limit":1, "datetime":"2018-01-01"}' -H 'Content-Type: application/json' -X POST -s|jq ".properties.found"

684

curl "https://sat-api.developmentseed.org/search/stac" -d '{"collection":"landsat-8",  "limit":1, "datetime":"2017-01-01"}' -H 'Content-Type: application/json' -X POST -s|jq ".properties.found"

558

Hi @drzhouq if you provide a single date to datetime it will search for matches just for that datetime, it's not a range by default. If you want a range, such as from that date until today you'll need to provide both beginning and ending datetime by using a slash, e.g.

"datetime": "2018-01-01/2018-05-16"

I thought it took current date as the ending date if an ending date is not provided. Thanks for the clarification and help.
