tokenize

问题 I have some items in my index (Solr. 4.4), which contain names like Foobar 135g , where the 135g refers to some weights. Searching for foobar or foobar 135 does work, but when I try to search for the exact phrase foobar 135g , nothing is found. I analysed the query inside the solr admin panel "Analysis". Here everything looks good. The fields are indexed correctly, the query is splitted correctly, and I get hits (indicated by this purple background on the tokens). But there has to be an issue

问题 If you have this code: "......".Split(new String[]{"...", ".."}, StringSplitOptions.None); The resulting array elements are: 1. "" 2. "" 3. "" Now if you reverse the order of the separators, "......".Split(new String[]{"..", "..."}, StringSplitOptions.None); The resulting array elements are: 1. "" 2. "" 3. "" 4. "" From these 2 examples I feel inclined to conclude that the Split method recursively tokenizes as it goes through each element of the array from left to right. However, once we

问题 Hi can somebody explain me please how to achieve higher score in search result for shorter phrase in compare with longer phrase? E.g. if I have two words ABCXXX and ABCXXXXX with edge ngram tokenizer and if I want to find ABC token score is the same . I would like to get higher score for ABCXXX and lower for ABCXXXXXX. Mapping looks like: { "settings": { "index": { "refresh_interval": "1m", "number_of_shards": "1", "number_of_replicas": "1", "analysis": { "filter": { "autocomplete_filter": {

问题 I am using Python's NLTK library to tokenize my sentences. If my code is text = "C# billion dollars; we don't own an ounce C++" print nltk.word_tokenize(text) I get this as my output ['C', '#', 'billion', 'dollars', ';', 'we', 'do', "n't", 'own', 'an', 'ounce', 'C++'] The symbols ; , . , # are considered as delimiters. Is there a way to remove # from the set of delimiters like how + isn't a delimiter and thus C++ appears as a single token? I want my output to be ['C#', 'billion', 'dollars', '

问题 I've written a simple string tokenizing program using pointers for a recent school project. However, I'm having trouble with my StringTokenizer::Next() method, which, when called, is supposed to return a pointer to the first letter of the next word in the char array. I get no compile-time errors, but I get a runtime error which states: Unhandled exception at 0x012c240f in Project 5.exe: 0xC0000005: Access violation reading location 0x002b0000. The program currently tokenizes the char array,

问题 I'm working on an end-of-semester project for a Programming languages course. The assignment is given below. I'm finishing writing it in Java and I'm having a lot of trouble writing in Prolog. I've been having a lot of trouble with Prolog so this question is as much looking for help with the assignment as it is trying to understand Prolog more. Any help that I can get would be GREATLY appreciated A sentence contains words, all occurring in a dictionary, that happen to be concatenated without

问题 How can I insert a char acter into a string exactly after 1 character? I need to insert '|' into the string after every other character. In other words (C++): "Tokens all around!" Turns into: "T|o|k|e|n|s| |a|l|l| |a|r|o|u|n|d|!" (no thats not an array) Thanks 回答1: std::string tokenize(const std::string& s) { if (!s.size()) { return ""; } std::stringstream ss; ss << s[0]; for (int i = 1; i < s.size(); i++) { ss << '|' << s[i]; } return ss.str(); } 回答2: I think I'd use a standard algorithm and

问题 I'm in the process of writing a string tokenizer without using strtok(). This is mainly for my own betterment and for a greater understanding of pointers. I think I almost have it, but I've been receiving the following errors: myToc.c:25 warning: assignment makes integer from pointer without a cast myToc.c:35 (same as above) myToc.c:44 error: invalid type argument of 'unary *' (have 'int') What I'm doing is looping through the string sent to the method, finding each delimiter, and replacing

问题 I have documents in Solr/Lucene (3.x) with a special copy field facet_headline in order to have an unstemmed field for faceting. Sometimes 2 ore more words are belong together, and this should be handled/counted as one word, for example "kim jong il". So the headline "Saturday: kim jong il had died" should be split into: Saturday kim jong il had died For this reason I decided to use protected words (protwords), where I add kim jong il . The schema.xml looks like this. <fieldType name="facet
