facet

问题 There are many examples of the use of facets based on the taxonomy index and on DocValues. But I need use as a hierarchy of categories (taxonomy) and Range queries (NumericDocValuesField) together. For example DrillSideways : DrillSideways ds = new DrillSideways (searcher, config, taxoReader); DrillSideways.DrillSidewaysResult result = ds.search (q, topScoreDocCollector); The second parameter of ds.search() is TopScoreDocCollector . FacetsCollector created inside ds.search() and not possible

问题 I need to facet inside n documents which are selected like ... ORDER BY something DESC LIMIT 100 Is that possible with Solr? How? 回答1: AFAIK no, that's not supported / implemented. Facets aren't really meant to be "stats" but a guidance to the end-user. Picture yourself browsing a faceted interface and seeing facets change whenever you change sort order or paging. Faceted browsing would be useless if it worked like that. I think this would be a nice feature for the StatsComponent though. 回答2:

问题 I have data with Country level stats over time. I use facet_wrap() to plot by Country but I want to order the plots based on only the most recent value (2015) in descending order. I've tried to use transform() but that orders only on the first values (2005). I think forcats::fct_reorder() could get me there but I have not been successful in inserting in any of the arguments for facet_wrap() . Is this even possible? I'd prefer not to have to do a grid_arrange() as this question suggests if

问题 After editing Discovery.xml located in C:\dspace-4.2-release\dspace\config\spring\api to add facet, which messages.xml should be edited to add a key, <message key="xmlui.ArtifactBrowser.SimpleSearch.filter.type">Type</message because I realized there are 10 messages.xml files in C:\dspace-4.2-release folder. Does anyone know which messages.xml should I add the key? This is for XMLUI Interface. 回答1: Given the following facet <bean id="searchFilterCourse" class="org.dspace.discovery

问题 Extending from this questions about locales And described in this question: What I really wanted to do was install a codecvt facet into the locale that understands UTF-16 files. I could write my own. But I am not a UTF expert and as such I am sure I would get it nearly correct; but it would break at the most inconvenient time. So I was wondering if there are any resources (on the web) of pre-build codecvt (or other) facets that can be used from C++ that are peer reviewed and tested? The

问题 In my analyzer chain, ShingleFilter comes after stopword filter. As mentioned in the docs, ShingleFilter handles position increments > 1 by inserting filler tokens (tokens with termtext "_"). For example : "please divide this sentence into biword shingles" Shingles of size 2 : please divide, divide _, _ sentence, sentence _, _ biword, biword shingles (assuming that "this, "into" are stopwords) I would like to eliminate those shingles with the filler tokens, i.e. my desired output contains

问题 So, I am trying to make a grid of plots that are faceted by three different variables. I can generate the grid of plots just fine, the only hitch I am having is that the order in which the labels is placed seems out of order. Here is a simple example of what I am doing: library(ggplot2) data(mtcars) qplot(mpg, wt, data=mtcars) + facet_grid(cyl +am ~ vs, labeller = label_both) which produces the following plot: Now, for the most part, the plot looks great, but for the labels on the right hand

问题 I have a dataset consisting of 3 variables (a, b, c) and one response (d). df <- structure(list(a = c(0.9973, 0.9965, 1.002, 1.0019, 1.001, 1.0031, 1.0005, 1.0009, 1.0007, 0.9977, 1.0004, 1.001, 0.9936, 0.9945, 1.0056, 1.0004, 0.9969, 0.9977, 1.001, 0.9876), b = c(-4.0841, -4.216, -4.1469, -4.1418, -4.1919, -4.1953, -4.3314, -4.1205, -4.2449, -4.0841, -4.276, -4.3396, -4.2885, -4.1386, -4.0689, -4.2229, -4.3886, -4.2267, -4.0344, -4.6152), c = c(32.04, 18.52, 26.01, 25.65, 21.44, 22.26, 21.8,

问题 Given: auto foo = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"s I can convert all the characters to lowercase by: use_facet<ctype<char>>(cout.getloc()).tolower(data(foo), next(data(foo), foo.size())); Live Example But this depends upon cout.getloc() containing the ctype<char> facet . Presuming that I'm using an unmodified cout can I assume that cout.getloc() will contain the facet ctype<char> or do I need to confirm this before use with: has_facet<ctype<char>>(cout.getloc()) 回答1: From cppreference: Each

问题 I'm trying to get ggplot to order my boxplots based on median value after splittin the data into several different facets. This is part of a larger Shiny app I've written. Under default parameters, I can generate three faceted boxplots that order correctly: boxData <- structure(list(Classification = structure(c(4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L,
