About the title of a search engine in the Java library in the "style function tool box" framework title
Implementing style function tool box: hot article title in the search engine in the Java class library
introduction:
In the current information explosion, search engines have become one of the main ways for people to obtain information.In order to improve the user experience of search engines, many developers use the Java class library to create powerful and efficient search engines.In this article, we will introduce how to use the Java class library to achieve a style functional tool box to improve the appearance and function of the search engine.We will also provide some Java code examples to help readers better understand the implementation method of the framework.
1. Introduce style function toolbox
The style function toolbox is a collection of various styles and functions in search engines.It can contain the following features:
-The highlight display of search results
- automatic completion
-D dynamic load more results
-Filler and sorter
-Searching history record
- language selection
-The theme selection, etc.
2. The search results are highlighted display example
Code example:
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class SearchResultFormatter {
public static String highlightSearchKeywords(String query, String content) {
String formattedContent = content;
try {
String[] keywords = query.split(" ");
for (String keyword : keywords) {
String patternString = "(?i)\\b(" + keyword + ")\\b";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(formattedContent);
while (matcher.find()) {
String matchedKeyword = matcher.group(1);
formattedContent = formattedContent.replace(matchedKeyword, "<span class=\"highlighted\">" + matchedKeyword + "</span>");
}
}
} catch (Exception e) {
e.printStackTrace();
}
return formattedContent;
}
}
The above example code demonstrates how to use the Java class library to display the keywords queried by the user in the search results page in the search results page.First of all, we use the regular expression mode to match the keywords in the user's query, and use the `span>` tag of HTML to wrap it.This will make the keywords in the search results page in the style table can be customized by custom style setting through the `Highlight 'class.
3. Automatically complete examples
Code example:
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;
public class AutoComplete {
private List<String> wordList;
public AutoComplete(List<String> wordList) {
this.wordList = wordList;
}
public List<String> getSuggestions(String prefix) {
return wordList.stream()
.filter(word -> word.startsWith(prefix))
.collect(Collectors.toList());
}
}
The above example code shows an automatic completion class that receives a string list as the input and returns the recommended word list that matches it according to the given prefix.This class uses the stream programming (Stream) function in Java 8 to obtain all words that start with a specified prefix through the filter operation, and collect the results into a new list and return.
in conclusion:
This article introduces how to implement a style functional tool box in the Java library to enhance the appearance and function of the search engine.We provide examples of highlighting and automatic Java code for search results to help readers understand the implementation principles of these functions.Using this style functional tool box, developers can build better and user -friendly search engines.At the same time, readers can also expand and add other functions based on this framework to meet their needs.
