A GravityView search that works initially but changes after opening an entry or following a navigation link can have a URL-handling problem. Track the exact value at each step. Rebuilding the data or loosening a filter will not fix a value that changed in transit.
Check the release context
GravityView 3.9.0 addressed special characters changing in search and entry-navigation links and added URL-encoding modifiers for get merge tags. Advanced Filtering 4.10.0 also fixed get-value filtering problems. Use compatible supported releases and review both changelogs when that extension participates in the affected View.
Those fixes provide a reason to test the integration, not proof that every custom link is correct. A theme snippet or manually assembled query string can still transform the value before GravityView receives it. Keep custom-link behavior separate from the plugin's own navigation.
Use four synthetic labels
Create staging entries labelled R&D, A+B, 50%, and Zone #2 in a searchable text field. Keep the field's stored value visible to the tester. Search for one exact value at a time and record the matching entry IDs before clicking any links.
For each case, copy the resulting navigation URL. Compare the browser's displayed address with a decoded query-parameter view, such as URLSearchParams in a controlled local test. Do not repeatedly decode a value until it looks familiar; that can hide double encoding.

These examples describe a value component, not an entire URL. Encoding the full address with a component encoder can damage its separators. Conversely, pasting unencoded user text after a query parameter name can create unintended parameters.
Trace the original search value through a URL component and back to the application before comparing result IDs. Synthetic explanatory visual.
Find the first point where the value changes
Compare four observations: the typed input, the stored field value, the generated link, and the decoded value received by the destination. Then compare the resulting entry IDs. If the destination gets the correct value but returns the wrong entries, investigate the filter rather than adding more encoding.
Test the View's native search and navigation separately from custom buttons or template links. A native path that passes while a custom link fails narrows the repair to that link builder. Keep the same search operator and visitor role for both tests so permissions do not masquerade as an encoding problem.
When creating links in custom JavaScript, use a URL object and its searchParams setter for the value. Pass the original value, not a string you already encoded. In server templates, follow the documented merge-tag modifier appropriate to the output context. Avoid stacking several modifiers without checking their individual outputs.
Encoding is not an access-control fix
Preserving a search string does not make it safe to insert into HTML, a database query, or another context. Use the framework's appropriate escaping and parameter handling separately. Do not bypass entry permissions because an encoded search fails for a public visitor.
Only run fixtures against your own authorized test records. Keep names, health details, and other private entry values out of URLs. Even a correctly encoded query can be retained in browser history, server logs, and analytics.
Finish with a round-trip test
Search each fixture, open one result, return to the View, and follow the available next or previous entry navigation. The value and expected entry set should remain stable throughout. Include a blank search to verify that clearing the filter also behaves as intended.
If the underlying responses are already inconsistent before navigation, use the entry field mapping guide. For a reproducible link-construction fault, HandL WP can trace the failing transition. Provide the synthetic value and sanitized URL rather than exporting real respondent records.
