## Processing Settings

::

Access these settings by clicking the gear icon at the bottom of your Knowledge Stack:

### Embedding Model
Choose how Msty understands your content:
- **Local**: Private, offline processing
- **Remote**: Enhanced accuracy via OpenAI
- Click to see all configured models

### Splitter Type
Choose how to divide your content:
- **Recursive Character**: Like chapters in a book
  - Best for normal documents
  - Keeps paragraphs together
  - Works well with mixed content
- **Sentence**: Like individual sentences
  - Perfect for technical docs
  - Keeps code blocks intact
  - Better for precise answers

### Chunk Settings
Control how Msty processes your text:

1. **Chunk Size**
   - Low: Quick, specific answers
   - Medium: Balanced (recommended)
   - High: More context
   - Highest: Full context

2. **Chunk Overlap**
   - Low: Minimal connection
   - Medium: Good balance
   - High: Strong connection
   - Highest: Maximum context

3. **Ignore Small Chunks**
   - Default: 50 characters
   - Filters out headers, footers
   - Skips single-line comments
   - Removes short metadata

Start with Medium settings - they work great for most documents! Adjust only if you notice issues with answer quality.

## Search Settings

Access these by clicking the sliders icon in the top right:

### Results Control
1. **Number of Chunks**
   - Default: 15 chunks
   - Adjust based on needs
   - More chunks = broader context
   - Fewer = focused answers

2. **Similarity Threshold**
   - Low to Highest options
   - Controls match strictness
   - Higher = more precise matches
   - Lower = broader results

## Managing Changes

::

### Save Options
- **Save Draft**: Store unfinished work
- **Compose**: Activate your stack
- **Three-dot Menu**:
  - "Compose new changes": Update content
  - "Recompose Stack": Apply setting changes

## When to Adjust Settings

1. **Content Issues**
   - Long documents → Increase chunk size
   - Missing context → Increase overlap
   - Too much noise → Raise similarity threshold
   - Short answers → Add more chunks

2. **Performance Tips**
   - Test with real questions
   - Change one setting at a time
   - Note what works best
   - Save successful configurations
