Krugle - User Interface and Experience

User Interface Overview

The user interface of Krugle, a tool for enterprise-scale software analysis and search, is designed to be intuitive and user-friendly, particularly for developers.

Search Interface

The core of Krugle’s interface is its search functionality. Users can enter keywords or specific search terms into the search box, and the system returns relevant results. For example, searching for a term like “getParameter” will display results that include the file name, language, project name, the last crawl date, and a snippet of the code with the search term highlighted.

Refining Searches

To make searches more precise, Krugle offers various facets in the left-hand margin. Users can refine their searches by project, document type, author, or date. This feature allows for targeted searches, such as finding instances of “getParameter” in Java files within a specific project like “Apache SOLR”.

Advanced Search Capabilities

Krugle also supports advanced search queries using qualifiers. These qualifiers enable users to search for keywords or tokens in specific parts of the code, such as function calls, class names, or comments. For instance, to find files with the term “Connection” in a function call sequence, users can enter the query functioncall:”Connection”.

Issue and Check-In Comment Search

In addition to code searches, Krugle indexes and makes searchable issue records from systems like JIRA and check-in comments. This allows users to search for issues by author, date, or project, and to find specific changes related to bug fixes or other activities.

AutoSearch Feature

Krugle’s AutoSearch feature automates the process of running queries at specified frequencies, summarizing results, and identifying changes. This is particularly useful for monitoring development activities over time and tracking specific code patterns or defect fixes.

Ease of Use

The interface is structured to be easy to use, with clear and descriptive labels. Each search generates a unique URL that can be saved or shared with colleagues, allowing multiple search results to be displayed in different browser tabs. This functionality enhances collaboration and makes it easier to manage multiple searches simultaneously.

Overall User Experience

Krugle’s user experience is centered around providing quick and accurate access to software and application technology. The tool is designed to help developers troubleshoot complex problems, disseminate code fixes, and share application insights in real-time. The continuous updating of the code index ensures that users have access to the most current information, making it easier to pinpoint critical code patterns, security vulnerabilities, and application issues.

Conclusion

In summary, Krugle’s user interface is streamlined for efficiency and clarity, making it a valuable tool for developers who need to search, analyze, and manage large volumes of code and related data.
