问题 I would like find the fastes way in R to indentify indexes of elements in Ytimes array which are closest to given Xtimes values. So far I have been using a simple for-loop, but there must be a better way to do it: Xtimes <- c(1,5,8,10,15,19,23,34,45,51,55,57,78,120) Ytimes <- seq(0,120,length.out = 1000) YmatchIndex = array(0,length(Xtimes)) for (i in 1:length(Xtimes)) { YmatchIndex[i] = which.min(abs(Ytimes - Xtimes[i])) } print(Ytimes[YmatchIndex]) 回答1: R is vectorized, so skip the for loop

问题 I am indexing a collection of xml document with the next structure: <mydoc> <id>1234</id> <name>Some Name</name> <experiences> <experience years="10" type="Java"/> <experience years="4" type="Hadoop"/> <experience years="1" type="Hbase"/> </experiences> </mydoc> Is there any way to create solr index so that it would support the next query: find all docs with experience type "Hadoop" and years>=3 So far my best idea is to put delimited years||type into multiValued string field, search for all

问题 I need help figuring out which query types to use in given situations. I think i'm right in saying that if i stored the word "FORD" in a lucene Field and i wanted to find an exact match i would use a TermQuery ?

问题 I'm very new to BASH Shell programming. Here's my issue, I need to split data from my file (with a semicolon delimiter) and search if a certain book exists. file contents: Harry Potter - The Half Blood Prince:J.K Rowling:40.30:10:50 The little Red Riding Hood:Dan Lin:40.80:20:10 Harry Potter - The Phoniex:J.K Rowling:50.00:30:20 Harry Potter - The Deathly Hollow:Dan Lin:55.00:33:790 Little Prince:The Prince:15.00:188:9 Lord of The Ring:Johnny Dept:56.80:100:38 Three Little Pig:Andrew Lim:89

问题 I have a question about a peculiar behavior I noticed in my custom analyzer (as well as in the fr.microsoft analyzer). The below Analyze API tests are shown using the “fr.microsoft” analyzer, but I saw the same exact behavior when I use my “text_contains_search_custom_analyzer” custom analyzer (which makes sense as I base it off the fr.microsoft analyzer). UAT reported that when they search for “femme” (singular) they expect documents with “femmes” (plural) to also be found. But when I tested

问题 I have the following CSS markup. .previous-container{ float:left; } .primary-commands { float:right; } Using the regex syntax search (?<=[\s,;])([a-zA-Z\-]+): it highlights the CSS property name as expected, however, upon clicking replace nothing is replaced. I have tried using group token syntax in replace line e.g. $[nth group] and any plain literal string replacement. No matter my attempts it will not replace the matched string with anything. I am using notepad++ version 6.7.5. Perhaps

问题 I want to add a spotlight search functionality - search results being displayed with rich contents like thumbnail etc in a drop down menu changing on each keyup event - just like the apple.com search - to a site, having data in MySQL InnoDB tables.

The data is spread into separate tables for categories, help pages, blog pages and so on. The search script must take

问题 Given a key: 'mykey' And given an object: Object {Mykey: "some value", ...} And using the following if (key in myObject) syntax to check for a match... How can I check matching strings regardless of capital letters? For example: key mykey should be matched to Mykey in the object even though the M is capitalized. I am aware of a function to do this: How to uppercase Javascript object keys? I was looking to see if there was another way. 回答1: You can create a function that does this, there's no

问题 I would like to check if any div contains all words entered in an input field. However, currently I am stuck in a situation that as soon as a space is entered, it starts all over, and thus sort of acts like an OR operator instead of an AND operator. Could anyone please push me in the right direction? Thanks a lot! This is what I have so far: <div class="search">aa ab ac ad</div> <div class="search">ab ba bb bc</div> <div class="search">bb cc dd ee</div> <script> function search(query) { var
