search

问题 I'm not well versed in front end web design or CSS. Using a pre-made template from Foundation, however my code for a search button is not aligning like the example button. Using this template: http://foundation.zurb.com/templates/workspace.html Can someone tell me how I can move the search button to the right as in pic where the blue button is located? This is what I am using now: <input type="submit" value="Search" style="float: right;"> Fiddle: Search button code <ul class="right"> <li

问题 I have a big xml file and I do not wish to parse it, I just want to store every single character between <information>...</information> , which are tags inside the xml file. How can I do this? 回答1: If the problem is that the data you're trying to extract will fit in memory, but the entire XML file won't, then use a streaming parser such as XPP. 回答2: You can't accurately find the characters in the <information> element without parsing the file. You could do something that works 99% of the time

问题 I´m using Lucene.NET 3.0.3 for indexing the content of word-, excel-, etc. documents and some custom fields for each document. If I index a field named "title" as Field.Index.NOT_ANALYZED the Lucene-Index stored the field in correct form. The hole title is stored in a single token. That´s what I want. e.g. title of document is "Lorem ipsum dolor" field in Lucene-index: "Lorem ipsum dolor" If I search using exact search in this field I get no results. My searchterm looks like: title:"Lorem

问题 I can't seem to figure this out My tree nodes have the following 3 string fields and 3 node fields which are left, middle and right. This is what I have public TreeNode findNode(String name) { TreeNode pointer = this.getRoot(); if (!(name.equals(pointer.getName()))) { pointer = pointer.getLeft(); findNode(name); pointer = pointer.getMiddle(); pointer = pointer.getRight(); } return pointer; } I see that the problem is that I keep reseting the pointer to root with every iteration but I think

问题 For example I have a list of words: men's package, moment, immensely How can I search in mysql sample text: "men's" and return only "men's package" I'm using this $str = str_replace("s", "%s", $str); If I search for "men's", it will only show: men's package but when I search for "mens" it will also show: men's package, moment, immensely 回答1: Most database back ends provide some sort of text search functionality that will take stuff like punctuation into account (postgres and MySQL both have

问题 I use a simple preg_match_all to find the occurrence of a list of words in a text. $pattern = '/(word1|word2|word3)/'; $num_found = preg_match_all( $pattern, $string, $matches ); But this also match subset of words like abcword123 . I need it to find word1 , word2 and word3 when they're occurring as full words only. Note that this doesn't always mean that they're separated by spaces on both sides, it could be a comma, semi-colon, period, exclamation mark, question mark, or another punctuation

问题 I have videoplayer app with filebrowser listing all videos on SD card Code inspired by i want get audio files in sd card Using ContentResolver, works as expected, but it does not update if the files on card change. I do not mean automatically, but after view/app restart. Not even reinstalling the application helped, still shows the same files. The deleted video file is not visible via PC nor it is possible to play it (This video cannot be played (translation)). I dumped the data and the

问题 Poor performance of autocomplete fields reduces their usefulness. If the client-side implementation has to call an endpoint that does heavy db lookup, the response time can easily get frustrating. One neat approach comes from AWS Case Study: IMDb. It used to come with a diagram (no longer available), but in a nutshell a prediction tree would be generated and stored for every combination that can resolve in a meaningful way. E.g. resolutions for sta would include Star Wars, Star Trek,

问题 EDIT: I answered my own question. I cant post it as an answer because I have less than 10 rep. I have included it as an edit under the line of ~~~~~~~~~~. I believe this question does not require a code sample as it is about the algorithm. not a specific implementation. Suppose you have a grid of nodes each of which are connected to four neighbours with edge weight one (i.e. there is no diagonal movement). The heuristic being used is Manhattan distance. The start is in the upper left corner,

问题 How could I search for a string in a text and add another string after it like the following: I want to search for example "John 3 2 G" in a text if it is there I want to add strings after it I met John 3 2 G yesterday and.. after run the program I met John 3 2 G and his brother yesterday and.. to be known that the numbers are not fixed, they are numbers but could be changed I used re.sub but in this case when the numbers are changing how could I do it ? My attempt: re.sub("John","John and
