One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchTo search X posts from Java, call the X API v2 Search Posts endpoint, authenticate with a bearer token, and choose either recent search or full-archive search based on the required time coverage and the access available to your developer account. Build a precise, URL-encoded query, request the fields your application needs, and follow each response’s pagination token. A robust client must also handle rate limits and partial errors.
Choose the search endpoint and confirm access
X API v2 has two Search Posts options. Recent search covers posts from the last seven days and is available to all developers. Full-archive search covers the complete archive, dating back to March 2006, and is available to pay-per-use and Enterprise customers. Access, account limits, and pricing can change, so verify the current terms for your account in the X Search Posts documentation before designing around historical results.
| Option | Time coverage | Access | Maximum per request | Maximum query length |
|---|---|---|---|---|
| Recent search | Last 7 days (X Developer Platform Search Posts documentation) | All developers, subject to current account access and limits | Up to 100 posts (X Developer Platform Search Posts documentation) | 512 characters (X Developer Platform Search Posts documentation) |
| Full-archive search | Complete archive dating back to March 2006 (X Developer Platform Search Posts documentation) | Pay-per-use and Enterprise customers; confirm current account eligibility | Up to 500 posts (X Developer Platform Search Posts documentation) | 1,024 characters (X Developer Platform Search Posts documentation) |
These are endpoint maximums, not guarantees that every request returns that many posts. Search access is an account and retention decision as well as an endpoint choice; do not assume that changing the URL grants archive access.
Set up Java authentication
Create an approved X developer account, a Project, and an App, then obtain an API bearer token. Include it in the HTTP Authorization header as Authorization: Bearer <TOKEN>. Store the actual token in an environment variable or a secret manager, not in Java source code or a committed configuration file. X’s Recent Search quickstart walks through access and the basic request setup.

Write a precise query
Search operators determine which posts match. Combine terms and operators deliberately, then URL-encode the complete query value before adding it to the request URL. Examples include:
from:usernameorto:usernameto constrain posts by account.lang:ento limit results by language.has:imagesorhas:linksto look for posts with those features."exact phrase"to match a phrase.-is:retweetto exclude reposts.
For example, a query such as "service outage" lang:en -is:retweet combines an exact phrase, a language filter, and an exclusion. Check the Search Posts query documentation for operator syntax and endpoint-specific query rules. Encoding matters: spaces, quotation marks, and other query characters must be represented safely in a URL rather than concatenated raw.

Request the fields your application needs
The default response is intentionally sparse: it includes id, text, and edit_history_tweet_ids. Ask for additional post fields explicitly when the application needs them, such as created_at, public_metrics, or author_id. If the application also needs author details, request the author_id expansion and the desired user fields. See the Recent Search quickstart for field and expansion examples.
Request only data the downstream feature will use. This keeps response handling focused and avoids treating omitted fields as if they had been returned. When parsing results, account for the fact that expanded user data is separate from the post objects and must be associated using identifiers.

Search responses can include a meta.next_token. Pass that value as pagination_token on the next request to retrieve another page. Continue until the response has no next token or the application’s own result limit has been reached. The Pagination documentation explains token-based pagination; the Java SDK also documents iterator support.
- Send the initial search request with the query and requested fields.
- Process the page’s post data and any included expansion data.
- Read
meta.next_token; if present, use it aspagination_tokenin the next request with the same search criteria. - Stop when no token is returned, or when the application’s configured time, page, or result bound is met.
For a large search, process each page incrementally—for example, persist or analyze its posts before fetching the next page—rather than accumulating the entire result set in memory. Define a stopping policy so a query that matches many posts cannot run indefinitely.

Choose the Java SDK or an HTTP client
The official xdevplatform/twitter-api-java-sdk supports API v2 operations, including recent and full-archive search, and provides typed API operations and documented retry handling. Its repository describes a built-in retry mechanism for rate limits; when called with a retry count, it can inspect rate-limit headers and wait for the reset after HTTP 429 responses.
A hand-written Java HTTP client gives direct control over transport, logging, request construction, and custom retry policy, but your code must implement response parsing, pagination, and rate-limit handling. The SDK can reduce that work, while a direct client may suit an application with specific transport or observability requirements. In either case, verify the library’s current release and compatibility against the repository before adopting it.

Handle rate limits, errors, and incomplete responses
X uses standard HTTP status codes. A 429 response means the request is rate limited or a usage cap has been exhausted; it does not necessarily mean the query syntax is invalid. Use the x-rate-limit-reset header to determine when to retry, and apply exponential backoff rather than immediately repeating requests. Keep retry counts bounded, and avoid retrying a request in a tight loop if the reset time or account allowance prevents success. See X Response Codes & Errors for status and error handling details.
Also inspect the response body on successful HTTP responses. A 200 response can contain both data and an errors array, meaning some requested resources did not resolve successfully. Process available data while recording or surfacing the associated errors, rather than assuming that HTTP success means every post or expansion is complete.
Quick Recap
- For 429, pause according to the reset header and backoff policy.
- For other non-success status codes, handle the returned status and error body explicitly instead of treating all failures as rate limits.
- For 200 responses with an
errorsarray, preserve usable results and account for unresolved resources. - For paginated jobs, make retry and resume behavior compatible with the current page token so a transient failure does not silently skip work.
