arrays - OR query in rethink -

-

is possible or search on values of array in rethink.

eg: have table called "post" field "tags" array. want or search on values of tags.

post1 { tags : ["young","agreesive"] }  post2 { tags : ["cricket","india"] }

give me posts contains tags "young" or "cricket" should return both posts.

as mlucy said, can use filter in conjunction or , contains documents specific tag.

if have array of tags, can following too:

var tags = ["young", "cricket"];  r.table('posts').filter(function (row) {   return r.expr(tags).contains(function (value) {      return row("tags").contains(value)    }); })

this more extensible using or.

multi index

you can create multi-index property. multi-indexes let lookup data of values in array. so, example:

r.table("posts").indexcreate("tags", {multi: true}) r.table("posts").getall("young", "cricket", {index: "tags"})

this query documents "young" , "cricket" tag, , it's more performant , cleaner using nested contains.

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...
