#1845: VSL-query can only capture last field, if using floats operand.
-------------------------+------------------------
Reporter: xcir | Type: defect
Status: new | Priority: normal
Milestone: | Component: varnishlog
Version: 4.1.1-beta1 | Severity: normal
Keywords: vsl-query |
-------------------------+------------------------
VSL-query was using the VNUM when vsl-query parse the float.[[BR]]

https://github.com/varnish/Varnish-
Cache/blob/1628f0b93e4ba725f2f26ca82a6e794229517475/lib/libvarnishapi/vsl_query.c#L148

But, VNUM does not care a string of multiple field. (ex: - Timestamp
Resp: 1453185650.045902 0.000848 0.000031 )[[BR]]

https://github.com/varnish/Varnish-
Cache/blob/c24650d0f19faaa2f9c629c9d79ccebb940f585b/lib/libvarnish/vnum.c#L104-L105

Therefore, vsl-query can only capture last field.
