TeXcore offers a robust, keyboard-driven interface to search, preview, and link equations inside your vault. This module consists of two main interfaces: an editor-integrated **Autocomplete Popup** and a dedicated **Search Modal**.
Trigger autocompletion anywhere in your notes by typing your configured trigger string (default is `\eqref`). A dropdown menu instantly pops up at your cursor, displaying all equations matching your query along with their parsed line numbers and live math previews.
If you reference an equation that has no identifier tag, TeXcore automatically generates a unique ID (e.g. `% id: eq-b5x3e2`), appends it before the closing `$$`, and inserts the resolved link to ensure referencing consistency.
Access the dedicated note-wide search dialog by triggering ++ctrl+p++ and running `Search equations in active note`. This modal provides an expanded viewport displaying equation previews on hover. It uses two search algorithms configurable in your [Autocomplete Settings](configuration/settings.md#autocomplete-search):
- **Fuzzy Search (Default)**: Matches partial strings and typos (e.g., query `intgl` matches `\integral` or `\int`) using Obsidian's internal `prepareFuzzySearch` utility.
- **Simple Search**: Matches exact substrings (e.g., query `int` matches `\int` and `point` but not `frac`) using Obsidian's `prepareSimpleSearch` utility.
When jumping to equation definitions via the autocomplete suggestion list, you can configure the editor target split layout in [Settings Reference](configuration/settings.md#open-location):
- **Vault Performance**: The search indexing index is scoped to the **active note only**. This prevents vault-wide scan lag, resulting in instant search evaluations even on low-end hardware.
- **Custom Triggers**: You can change the trigger string in [Autocomplete & Search Settings](configuration/settings.md#autocomplete-search) to `#eq` or `@eq` if you want to avoid overlaps with other LaTeX parser plugins.
