Filtering on pdf reports

Hi, when in a dashboard I select share -> pdf reports - post url to create a report, i get this url:
/api/reporting/generate/printablePdfV2?jobParams=(browserTimezone:America/Santiago,layout:(dimensions:(height:1463.984375,width:1692.5),id:preserve_layout),locatorParams:!((id:DASHBOARD_APP_LOCATOR,params:(dashboardId:bb9342a0-d32e-11ed-a3c7-f3cc8fbb9ac2,preserveSavedFilters:!t,timeRange:(from:now-30d,to:now),useHash:!f,viewMode:view),version:'7.17.5')),objectType:dashboard,title:'Anomalias dashboards',version:'7.17.5')

how can I modify this url to add a filter like:

hostname.keyword:my-hostname

so I get only the data of my-hostname in the report.

Thanks.

If you save the filter with the dashboard it will be preserved in the report. Is that not an option?

Hi, no the filter its not saved like in older versions, but just managed to add a query in rison, after viewMode:view

,filters:!((meta:(alias:null,disabled:!f,key:<field>,negate:!f,params:(query:<value>),type:phrase),query:(match_phrase:(<field>:<value>))))
