### Translation

**What does YaCy offer to an OSINT researcher?**

YaCy is a decentralized search engine operating on peer-to-peer (P2P) technology. It allows users to index websites independently and share results through a decentralized network, without centralized control from large corporations. For OSINT (Open Source Intelligence) researchers, YaCy offers several significant advantages:

### 1. **Privacy and Anonymity**

YaCy operates without centralized servers, making search queries and results less traceable. This is useful for OSINT researchers who often deal with sensitive information or prefer that their queries are not monitored by third parties or organizations.

### 2. **Complete Control over Indexing**

With YaCy, researchers can create their own indexes by selectively indexing the resources they need for analysis. This allows them to gather data from specific websites or domains, making their work more efficient and targeted.

### 3. **Collaboration with Other Researchers**

YaCy is a decentralized network that allows researchers to share indexed data with one another. This is helpful for finding information that others have already indexed, saving time and expanding the scope of available data.

### 4. **Local Data Storage and Analysis**

Unlike traditional search engines, YaCy allows for the local storage of indexed data. This enables detailed analysis of the collected information without the need to repeatedly query external search engines.

### 5. **Censorship Resistance**

Since YaCy is decentralized, it is difficult to control or censor, unlike traditional search engines that may face censorship in certain countries or regions. This makes YaCy particularly useful for OSINT researchers working under information blockades.

### 6. **Tools for Customized Search**

OSINT researchers can tailor search parameters according to their needs, create custom rules for filtering, and save search results for further analysis. This makes YaCy a flexible tool for individual tasks in search work.

### 7. **Access to the "Deep Web"**

YaCy allows researchers to find information from lesser-known or poorly indexed resources that typically do not appear in the results of traditional search engines. This opens access to hard-to-find information using conventional methods.

### Conclusion

YaCy is a valuable tool for OSINT researchers who require private, flexible, and controlled search processes, without reliance on centralized search engines. This solution can greatly enhance the effectiveness of open-source intelligence gathering, offering full control over data indexing and search.
