The literature search has identified several studies directly addressing how search query time affects user experience and usage in online search systems akin to Google Scholar [4, 6, 13, 15, 16, 33].

These studies highlight significant implications of search latency on user behavior, satisfaction, and stress levels. For instance, increased query time has been shown to influence user preference, leading to potential abandonment or reduced interaction with the system [4, 6]. Papers such as [13] and [15] offer detailed experimental results demonstrating how system delays under time constraints impact users' search strategies and document engagement. Moreover, research like [16] and [33] delineates the physiological and behavioral adjustments users make in response to system delays, emphasizing the critical nature of optimizing search speed to enhance overall user experience. These findings underscore the importance of minimizing search query times to maintain and improve user interaction with systems.

For the topic of interest, the most significant categories should focus on the direct investigation of the impact of search query time on user experience within systems similar to Google Scholar, as well as exploring the broader implications and nuances of search latency and user satisfaction. This organization will provide a detailed breakdown of how these issues are studied and related in the context of information retrieval and user interaction.

Title 1: "Direct Impact of Search Query Time on User Experience"
Description: Papers that explicitly examine how search query time affects user experience and usage in online search systems resembling Google Scholar.
References: [4]

Title 2: "In-depth Analysis of Search Latency Effects on User Behavior"
Description: Studies rigorously exploring how different aspects of search latency influence user behavior, engagement, and satisfaction.
References: [1, 2, 7, 10, 11, 16, 21, 31]

Title 3: "Search Interface and System Delays"
Description: Research investigating how system performance and delays impact user satisfaction, stress response, and behavior during searches.
References: [6, 8, 13, 15, 16, 33, 35]

Title 4: "User Coping Mechanisms and Perceptions under Time Pressure"
Description: Studies focusing on how perceptions and users' adjustments to time constraints or perceived delays affect their interactions with search systems.
References: [23, 25, 26, 33]

These categories aim to encapsulate the nuances of latency impacts on user experience, focusing on sensitivity to delays, modifications in search behavior, and broader psychological effects, which are crucial for optimizing search systems and understanding user interactions within them.

So far, I've closely analyzed 460 of the most promising papers, and I've found ~17-45 papers with relevant abstracts, which is probably more than 90% of all that exist.
