c# - NEST Elasticsearch query value between 2 field names -

-

i want convert following sql query elasticsearch nest query:

select * table1 20 between minage , maxage

so far nest query looks ("20" value client):

var result5 = client.search<person>(b => b         .filter(ff => ff                 .range(n => n                     .onfield(f => f.minage)                     .greater(20)                 )             )         .filter(ff => ff                 .range(n => n                     .onfield(f => f.maxage)                     .lower(???)  // how specify max value fieldname?                 )             ); 

   .filter(ff => ff             .range(n => n                 .onfield(f => f.minage)                 .greater(x)             ) && ff             .range(n => n                 .onfield(f => f.maxage)                 .lower(x)             )         )

in way have x -> between minage , maxage. x must greater minage , lower maxage in same time. hope helps!

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
